The HyperText Transfer Protocol (HTTP) is a protocol (a set of rules that describe how information is exchanged on a network) that allows a web browser and a web server to "talk" to each other using the ISO Latin1 alphabet, which is ASCII with extensions for European languages.
HTTP is based on a request/response model. The client connects to the server and sends a request to the server. The request contains a request method, URI, and protocol version. The client then sends some header information. The server's response includes the return of the protocol version, status code, followed by a header that contains server information, and then the requested data. The connection is then closed.
The Netscape FastTrack Server 3.01 supports HTTP 1.1. Previous versions of the server supported HTTP 1.0. The server is conditionally compliant with the HTTP 1.1 proposed standard, as approved by the Internet Engineering Steering Group (IESG) and the Internet Engineering Task Force (IETF) HTTP working group. For more information on the criteria for being conditionally compliant, see the Hypertext Transfer Protocol--HTTP/1.1 specification (RFC 2068) at:
http://www.ietf.org/html.charters/http-charter.html |
This chapter provides a short introduction to a few HTTP basics. For more information on HTTP, see the IETF home page at:
http://www.ietf.org/home.html |
A request from a client to a server includes the following information:
A client can request information using a number of methods. The commonly used methods include the following:
The client can send header fields to the server. Most are optional. Some commonly used request headers are shown in Table A-1
| Request Header | Description |
|---|---|
| Accept | The file types the client can accept. |
| Authorization | Used if the client wants to authenticate itself with a server; information such as the user name and password are included. |
| User-agent | The name and version of the client software. |
| Referer | The URL of the document where the user clicked on the link. |
| Host | The Internet host and port number of the resource being requested. |
If the client has made a POST or PUT request, it can send data after
the request header and a blank line. If the client sends a GET or HEAD
request, there is no data to send; the client waits for the server's
response.
A.2 Responses
The server's response includes the following:
When a client makes a request, one item the server sends back is a status code, which is a three-digit numeric code. There are four categories of status codes:
Table A-2 contains some common status codes.
| Status Code | Meaning |
|---|---|
| 200 | OK; successful transmission. This is not an error. |
| 302 | Found. Redirection to a new URL. The original URL has moved. This is not an error; most browsers will get the new page. |
| 304 | Use a local copy. If a browser already has a page in its cache, and the page is requested again, some browsers (such as Netscape Communicator) relay to the web server the "last-modified" timestamp on the browser's cached copy. If the copy on the server is not newer than the browser's copy, the server returns a 304 code instead of returning the page, reducing unnecessary network traffic. This is not an error. |
| 401 | Unauthorized. The user requested a document but didn't provide a valid user name or password. |
| 403 | Forbidden. Access to this URL is forbidden. |
| 404 | Not found. The document requested isn't on the server. This code can also be sent if the server has been told to protect the document by telling unauthorized people that it doesn't exist. |
| 500 | Server error. A server-related error occurred. The server administrator should check the server's error log to see what happened. |
The response header contains information about the server and information about the document that will follow. Common response headers are shown in Table A-3.
| Response Header | Description |
|---|---|
| Server | The name and version of the web server. |
| Date | The current date (in Greenwich Mean Time). |
| Last-modified | The date when the document was last modified. |
| Expires | The date when the document expires. |
| Content-length | The length of the data that follows (in bytes). |
| Content-type | The MIME type of the following data. |
| WWW-authenticate | Used during authentication and includes information that tells the client software what is necessary for authentication (such as user name and password). |
The server sends a blank line after the last header field. The server then sends the document data.
The internationalized version of the Netscape FastTrack Server contains
special features tailored for the non-U.S. environment.
B.1 General information
The following information covers the international considerations for general server capabilities, including:
If you want to type 8-bit data into the Server Manager or the
administration server forms, you need to be aware of the issues in this
section.
B.1.1.1 File or directory names
If a file or directory name is to appear in a URL, it cannot contain
8-bit or multi-byte characters.
B.1.1.2 LDAP users and groups
For email addresses, use only those characters permitted in RFC 822 (ftp://ds.internic.net/rfc/rfc822.txt). User ID and password information must be stored in ASCII.
If you use a local database, you can enter 8-bit and multi-byte characters, but you should standardize on one character set. If you use more than one character set in the same database, it can cause display problems.
If you must use 8-bit or multi-byte characters in your directory database, you should store them in UTF-8 for future compatibility with the Netscape Directory Server version 3.x. To make sure you enter characters in the correct format, use a UTF-8 form-capable client (such as Netscape Communicator) to input 8-bit or double-byte data.
If you let users access their own user and group information, they will
need to use a UTF-8 form-capable client.
B.1.2 Using the accept language header
When clients contact a server using HTTP 1.1, they can send header information that describes the various languages they accept. You can configure your server to parse this language information.
For example, suppose this feature is set to on, and a client configured to send the accept language header sends it with the value en,fr. Now suppose that the client requests the following URL:
http://www.mozilla.com/home.html |
The server first looks for:
http://www.mozilla.com/en/home.html |
If it does not find that, it looks for:
http://www.mozilla.com/fr/home.html |
If that is not available either, and a ClientLanguage (call it xx) is defined in the magnus.conf file, the server tries:
http://www.mozilla.com/xx/home.html |
If none of these exist, the server tries:
http://www.mozilla.com/home.html |
When you use server-side JavaScript with the international version of
the server, you have additional things to consider when compiling
applications and using databases. For example, you can specify the
language of the JavaScript application one of two ways: using the
compiler, or using the HTML <META> tag.
B.2.1 Specifying the character set for the compiler
For the international version, the server-side JavaScript compiler (jsac) has a -l option called charSet. This option specifies the character set being used in the input HTML files. The value for charSet is one of the following character set names shown in Table B-1.
| Language | Value for charSet |
|---|---|
| Western European | iso-8859-1 |
| Central European | iso-8859-2 |
| Cyrillic | iso-8859-5 |
| Japanese | iso-2022-jp, x-sjis, x-euc-jp |
| Korean | iso-2022-kr, x-euc-kr |
| Simplified Chinese | x-gb2312 |
| Traditional Chinese | x-big5, x-euc-ch |
| Greek | iso-8859-7 |
| Turkish | iso-8859-9 |
To use this option, use the following format:
jsac [-cdv] [-l charSet] -o binaryFile [-i] inputFile1 [-i] inputFile2 ... jsac [-cdv] -o binaryFile -f includeFile jsac -h |
Options
Table B-2 shows the options for the compiler.
| Option | Usage |
|---|---|
| -c | Check only; do not generate binaryFile |
| -v | Enable verbose output |
| -d | Enable debug output |
| -o | Name of binaryFile (output file) |
| -i | Name of inputFile (use if the input filename starts with a switch character) |
| -f | Name of includeFile (has input filenames, separated by white space) |
| -l | Name of charSet (for example, iso-8859-1, x- sjis, euc-kr) |
| -h | Display this help |
The possible filename extensions are summarized in Table B-3.
| Extension | File Type |
|---|---|
| .html or .htm | HTML source file (may include JavaScript) |
| .js | JavaScript source file |
| .web | Binary output file |
When you specify the language using the compiler option, you can only
specify one language. If you want to specify multiple languages, you
can use the <META> tag in the individual files.
B.2.2 Specifying the character set with the <META> tag
You can also use the <META> tag to specify the character set information. For example, if you put the following statement into the header (between <HEAD> and </HEAD> in a JavaScript program, the server-side JavaScript compiler (jsac) considers the file to be written in x-sjis.
<META HTTP-EQUIV="Content-Type" CONTENT="test/html; CHARSET=x-sjis"> |
If the character set specified in the <META> tag is different from the character set specified by the compiler's charSet option, the character set specified by the compiler option is used.
absolute path: The entire pathname for a file on a
given computer. For example, /usr/netscape/suitespot/docs/index.html is
an absolute path where /docs/index.html is a relative path. See also
path and pathname.
ACL: Access Control List. A mechanism for defining
which users have access to your server. You can define ACL rules that
are specific to a particular file or directory, granting or denying
access to one or more users and groups.
Access control: Functionality provided by Netscape
FastTrack Server that allows you to control client access to files on
your web server. Access control lets you determine who can access the
server based on authentication requirements you define.

Association. Includes 256 characters that can accomodate English as
well as other Latin-derived alphabets. Files created using ASCII text
can be viewed on any platform.
authentication: Allows clients to verify that they are
connected to an SSL-enabled server, preventing another computer from
impersonating the server or attempting to appear SSL-enabled when it
isn't.
authorization: The granting of access to an entire
server or particular files and directories on it. Authorization can be
restricted by criteria including hostnames and IP addresses.
browser : See web client.

which only the intended recipient can decrypt.
client : Software that sends requests to a server;
usually over a network. Also see web client.
client/server architecture : A network architecture
where each computer or process acts as either a client or a server.
Servers are computers or processes dedicated to managing information,
applications, and devices that make up the network, such as printers
and web sites. Clients are workstations or applications that send
requests to servers on the network, such as web browsers.
client-side applications: Applications run by the
client application and on the client's host machine.
collection: A database that contains information about
documents, such as word list and file properties. Collections are used
by the search function to retrieve documents matching specified search
criteria.

DNS: Domain Name System. The system that machines on a
network use to associate standard IP addresses (such as 198.93.93.10)
with hostnames (such as www.netscape.com). Machines normally get this
translated information from a DNS server, or they look it up in tables
maintained on their systems. DNS is distributed and replicated
worldwide across the Internet. See also, fully qualified domain name.
DNS alias: A hostname that the DNS server knows points
to a different host--specifically a DNS CNAME record. Machines always
have one real name, but they can have one or more aliases. For example,
an alias such as www.yourdomain.domain might point to a real machine
called realthing.yourdomain.domain where the server currently exists.
document root: A directory on the server machine that
contains the files, images, and data you want to present to users
accessing the server.
domain : A domain is a subset of the Internet from
which clients access a domain name server. A domain represents a group
of clients accessing the Internet. Some common domains are .com, .gov,
and .edu. The term domain is sometimes used to refer to the subdomain
and the domain in combination. For example, although in
www.mozilla.com, mozilla is the subdomain and com is the domain, the
word domain could also be used to refer to mozilla.com.
domain name : A string characterized by multiple
components separated by periods. Represents a domain on the Internet.
For example, everything to the right of the @ sign in an email address
is a domain name, such as in the email address joeb@mozilla.com where
the domain name is mycorp.com. See also DNS.
drop word: See stop word.
encryption: The process of transforming information so
it can't be decrypted or read by anyone but the intended recipient.

document, specified by the remote server.
extranet : An extension of a company's intranet onto
the Internet, to allow specific customers, suppliers, and remote
workers access to the data.
fancy indexing : A method of indexing that provides
more information than simple indexing. Fancy indexing displays a list
of contents by name with file size, last modification date, and an icon
reflecting file type. Because of this, fancy indexes might take longer
than simple indexes for the client to load.
file extension : The last part of a filename that
typically defines the type of file. For example, in the filename
index.html the file extension is html.
file type : The format of a given file. For example, a
graphics file is not the same file type as a text file. File types are
usually identified by the file extension (.gif or .html).
firewall : A network configuration, usually both
hardware and software, that protects networked computers within an
organization from outside access. Firewalls are commonly used to
protect information such as a network's email and data files within a
physical building or organization site.
flexible log format : A format used by the server for
entering information into the access logs.
FTP : File Transfer Protocol. An Internet protocol
that allows files to be transferred from one computer to another over a
network. fully qualified domain name The entire domain name, including
the name of the computer, subdomain, and domain, for example,
www.mozilla.com where www is the computer name, mozilla is the
subdomain and com is the domain.
GIF : Graphics Interchange Format. A cross-platform
image format originally created by CompuServe. GIF files are usually
much smaller in size than other graphic file types (BMP, TIFF). GIF is
one of the most common interchange formats. GIF images are readily
viewable on Unix, Microsoft Windows, and Apple Macintosh systems.
hard restart : The termination of a process and its
subsequent restart. See also soft restart.
hardware : Articles made of physical material, such as
computers and their components (mechanical, electrical, and
electronic). Software and electronic files are excluded. The physical
computer on which you install Netscape FastTrack Server is hardware.
home page : A document that exists on the server and
acts as a catalog or entry point for the server's contents. The
location of this document is defined within the server's configuration
files.
hostname : A name for a machine in the form
machine.subdomain.domain, which is translated into an IP address. For
example, www.mozilla.com is the machine www in the subdomain netscape
and com domain. This term is often used in place of the fully qualified
domain name.
HTML : Hypertext Markup Language. A formatting
language used for documents on the World Wide Web. HTML files are plain
text files with formatting codes that tell browsers such as the
Netscape Navigator how to display text, position graphics and form
items, and display links to other pages.

exchanging information between HTTP servers and clients.
HTTP-NG: The next generation of HyperText Transfer
Protocol. HTTPD An abbreviation for the HTTP daemon, a program that
serves information using the HTTP protocol. The Netscape FastTrack
Server is often called an HTTPD.
HTTPS : A secure version of HTTP, implemented using
the Secure Sockets Layer, SSL.
hypertext : Text linked across a potentially unlimited
number of computers. Clicking a link on a hypertext document takes the
user to another document, which contains links to other documents.
Hypermedia is often used to extend the definition to include sound,
graphics, and other electronic file formats.
imagemap : A process that makes areas of an image
active, letting users navigate and obtain information by clicking the
different regions of the image with a mouse. Imagemap can also refer to
a CGI program called "imagemap," which is used to handle imagemap
functionality in other HTTPD implementations.
inittab : A Unix file listing programs that need to be
restarted if they stop for any reason It ensures that a program runs
continuously. Because of its location, it is also called /etc/inittab.
This file isn't available on all Unix systems.
intelligent agent : An object within a server that
performs various requests (such as HTTP, NNTP, SMTP, and FTP requests)
on behalf of the user. In a sense, the intelligent agent acts as a
client to the server, making requests that the server fulfills.
Internet : Worldwide network of computers
communicating over TCP/IP.
Internet address : See URL.
Internet Protocol : The base of TCP/IP, which defines
how sending and receiving packets of information over the physical
network takes place. Hosts and gateways use IP as the mechanism to
route Internet data. Higher level protocols must reliably handle the
data, such as TCP.

You must define your news server host to use agent services on your
server.
NSAPI : See Server Plug-in API.
parsed HTML : The web server processes any directions
encoded in parsed HTML and sends the results to the requesting browser
instead of the original file. By default, the Netscape FastTrack Server
identifies files containing parsed HTML by the file extension .shtml.
Parsed HTML may contain lines that tell the server to include the
file's last-modified time or other information.
password file : A file on Unix machines that stores
Unix user login names, passwords, and user ID numbers. It is also known
as /etc/passwd, because of where it is kept.

programs that are run when the machine starts. This file is also called
/etc/rc.2.d because of its location.
redirection : A system by which clients accessing a
particular URL are sent to a different location, either on the same
server or on a different server. This system is useful if a resource
has moved and you want the clients to use the new location
transparently. It's also used to maintain the integrity of relative
links when directories are accessed without a trailing slash.
resource : Any document (URL), directory, or program
that the server can access and send to a client that requests it.

files. A soft restart sends the process the HUP signal (signal number
one). The process itself does not die, as it does in a hard restart.
software : All of the non-hardware components of a
computer system including programs, databases, and processes. Netscape
FastTrack Server and Netscape Communicator are software.
SSL : Secure Sockets Layer. A software library
establishing a secure connection between two parties (client and

stop word : A word identified to the search function
as a word not to search on. This typically includes such words as the,
a, an, and. Also referred to as drop words.
strftime : A function that converts a date and a time
to a string. It's used by the server when appending trailers. strftime
has a special format language for the date and time that the server can
use in a trailer to illustrate a file's last-modified date.
superuser : The most privileged user available on Unix
machines (also called root). The superuser has complete access
privileges to all files on the machine.

current state of system resource usage.
top-level domain authority : The highest category of
hostname classification, usually signifying either the type of
organization the domain is (for example, .com is a company, .edu is an
educational institution) or the country of its origin (for example, .us
is the United States, .jp is Japan, .au is Australia, .fi is Finland,
and so on).
uid : A unique number associated with each user on a
Unix system.
URI: Uniform Resource Identifier. A file identifier
that provides an additional layer of security by using an abbreviated
URL. The first part of the URL is substituted with a URL mapping that
hides the file's full physical pathname from the user. See also URL
mapping.
URL: Uniform Resource Locator. The addressing system
used by the server and the client to request documents. A URL is often
called a location. URL format is

updates a URL database that has been damaged by a software failure, a
system crash, a disk breakdown, or a full file system.
URL mapping: The process of mapping a document
directory's physical pathname to a user-defined alias so that files
within the directory need only refer to the directory's alias instead
of the file's full physical pathname. Thus, instead of identifying a
file as usr/Netscape/SuiteSpot/docs/index.html, you could identify the
file as /myDocs/index.html. This provides additional security for a
server by eliminating the need for users to know the physical location
of files on the server.
user name : A string used to identify a user, for
example, administrator or jdoe.
web client : Software, such as Netscape Communicator,
used to request and view or run World Wide Web material. Also known as
a browser program. Also see client.
web publishing : The capability of server clients to
access and manipulate server files, editing and publishing documents
remotely. Web publishing provides document version control, link
management, search, access control, and agent services to server users.
Web Application Interface (WAI) : An easy-to-program mechanism for extending the Enterprise server's functionality with CORBA-compliant services that are tightly integrated with the web server. WAI can be used to compose services in C, C++, and Java that customize the functionality of the server.
