-
-<p>The CGI (Common Gateway Interface) defines a way for a web server
-to interact with external content-generating programs, which are often
-referred to as CGI programs or CGI scripts. It is the simplest, and
-most common, way to put dynamic content on your web site. This
-document will be an introduction to setting up CGI on your Apache web
-server, and getting started writing CGI programs.</p>
-
-<hr>
-<h2><a name="configuringapachetopermitcgi">Configuring Apache to
-permit CGI</a></h2>
-
-<p>In order to get your CGI programs to work properly, you'll need to
-have Apache configured to permit CGI execution. There are several ways
-to do this.</p>
-
-<h3><a name="scriptalias">ScriptAlias</a></h3>
-
-<p>The <code>ScriptAlias</code> directive tells Apache that a
-particular directory is set aside for CGI programs. Apache will assume
-that every file in this directory is a CGI program, and will attempt to
-execute it, when that particular resource is requested by a client.</p>
-
-<p>The <code>ScriptAlias</code> directive looks like:</p>
-
-<pre>
- ScriptAlias /cgi-bin/ /usr/local/apache/cgi-bin/
-</pre>
-
-<p>The example shown is from your default <code>httpd.conf</code>
-configuration file, if you installed Apache in the default location.
-The <code>ScriptAlias</code> directive is much like the
-<code>Alias</code> directive, which defines a URL prefix that is to
-mapped to a particular directory. <code>Alias</code> and
-<code>ScriptAlias</code> are usually used for directories that are
-outside of the <code>DocumentRoot</code> directory. The difference
-between <code>Alias</code> and <code>ScriptAlias</code> is that
-<code>ScriptAlias</code> has the added meaning that everything under
-that URL prefix will be considered a CGI program. So, the example above
-tells Apache that any request for a resource beginning with
-<code>/cgi-bin/</code> should be served from the directory
-<code>/usr/local/apache/cgi-bin/</code>, and should be treated as a CGI
-program.</p>
-
-<p>For example, if the URL
-<code>http://dev.rcbowen.com/cgi-bin/test.pl</code> is requested,
-Apache will attempt to execute the file
-<code>/usr/local/apache/cgi-bin/test.pl</code> and return the output.
-Of course, the file will have to exist, and be executable, and return
-output in a particular way, or Apache will return an error message.</p>
-
-<h3><a name="cgioutsideofscriptaliasdirectories">CGI outside of
-ScriptAlias directories</a></h3>
-
-<p>CGI programs are often restricted to <code>ScriptAlias</code>'ed
-directories for security reasons. In this way, administrators can
-tightly control who is allowed to use CGI programs. However, if the
-proper security precautions are taken, there is no reason why
-CGI programs cannot be run from arbitrary directories. For example,
-you may wish to let users have web content in their home directories
-with the <code>UserDir</code> directive. If they want to have their
-own CGI programs, but don't have access to the main
-<code>cgi-bin</code> directory, they will need to be able to run CGI
-programs elsewhere.</p>
-
-<h3><a name="explicitlyusingoptionstopermitcgiexecution">Explicitly using
-Options to permit CGI execution</a></h3>
-
-<p>You could explicitly use the <code>Options</code> directive, inside
-your main server configuration file, to specify that CGI execution was
-permitted in a particular directory:</p>
-
-<pre>
- <Directory /usr/local/apache/htdocs/somedir>
- Options +ExecCGI
- </Directory>
-</pre>
-
-<p>The above directive tells Apache to permit the execution of CGI
-files. You will also need to tell the server what files are CGI files.
-The following <code>AddHandler</code> directive tells the server
-to treat all files with the <code>cgi</code> or <code>pl</code>
-extension as CGI programs:</p>
-
-<pre>
- AddHandler cgi-script cgi pl
-</pre>
-
-<h3><a name="htaccessfiles">.htaccess files</a></h3>
-
-<p>A <code>.htaccess</code> file is a way to set configuration
-directives on a per-directory basis. When Apache serves a resource, it
-looks in the directory from which it is serving a file for a file
-called <code>.htaccess</code>, and, if it finds it, it will apply
-directives found therein. <code>.htaccess</code> files can be permitted
-with the <code>AllowOverride</code> directive, which specifies what
-types of directives can appear in these files, or if they are not
-allowed at all. To permit the directive we will need for this purpose,
-the following configuration will be needed in your main server
-configuration:</p>
-
-<pre>
- AllowOverride Options
-</pre>
-
-<p>In the <code>.htaccess</code> file, you'll need the following
-directive:</p>
-
-<pre>
- Options +ExecCGI
-</pre>
-
-<p>which tells Apache that execution of CGI programs is permitted in
-this directory.</p>
-
-<hr>
-<h2><a name="writingacgiprogram">Writing a CGI program</a></h2>
-
-<p>There are two main differences between ``regular'' programming, and
-CGI programming.</p>
-
-<p>First, all output from your CGI program must be preceded by a
-MIME-type header. This is HTTP header that tells the client what sort
-of content it is receiving. Most of the time, this will look like:</p>
-
-<pre>
- Content-type: text/html
-</pre>
-
-<p>Secondly, your output needs to be in HTML, or some other format that
-a browser will be able to display. Most of the time, this will be HTML,
-but occasionally you might write a CGI program that outputs a gif
-image, or other non-HTML content.</p>
-
-<p>Apart from those two things, writing a CGI program will look a lot
-like any other program that you might write.</p>
-
-<h3><a name="yourfirstcgiprogram">Your first CGI program</a></h3>
-
-<p>The following is an example CGI program that prints one line to your
-browser. Type in the following, save it to a file called
-<code>first.pl</code>, and put it in your <code>cgi-bin</code>
-directory.</p>
-
-<pre>
- #!/usr/bin/perl
- print "Content-type: text/html\r\n\r\n";
- print "Hello, World.";
-</pre>
-
-<p>Even if you are not familiar with Perl, you should be able to see
-what is happening here. The first line tells Apache (or whatever shell
-you happen to be running under) that this program can be executed by
-feeding the file to the interpreter found at the location
-<code>/usr/bin/perl</code>. The second line prints the content-type
-declaration we talked about, followed by two carriage-return newline
-pairs. This puts a blank line after the header, to indicate the end of
-the HTTP headers, and the beginning of the body. The third line prints
-the string ``Hello, World.'' And that's the end of it.</p>
-
-<p>If you open your favorite browser and tell it to get the address</p>
-
-<pre>
- http://www.example.com/cgi-bin/first.pl
-</pre>
-
-<p>or wherever you put your file, you will see the one line
-<code>Hello, World.</code> appear in your browser window. It's not very
-exciting, but once you get that working, you'll have a good chance of
-getting just about anything working.</p>
-
-<hr>
-<h2><a name="butitsstillnotworking">But it's still not
-working!</a></h2>
-
-<p>There are four basic things that you may see in your browser when
-you try to access your CGI program from the web:</p>
-
-<dl>
-<dt>The output of your CGI program</dt>
-<dd>Great! That means everything worked fine.<br><br></dd>
-
-<dt>The source code of your CGI program or a "POST Method Not Allowed"
-message</dt>
-<dd>That means that you have not properly configured
-Apache to process your CGI program. Reread the section on <a
-href="#configuringapachetopermitcgi">configuring Apache</a> and try to
-find what you missed.<br><br></dd>
-
-<dt>A message starting with "Forbidden"</dt> <dd>That means that there
-is a permissions problem. Check the <a href="#errorlogs">Apache
-error log</a> and the section below on <a
-href="#filepermissions">file permissions</a>.<br><br></dd>
-
-<dt>A message saying "Internal Server Error"</dt> <dd>If you check the
-<a href="#errorlogs">Apache error log</a>, you will probably find
-that it says "Premature end of script headers", possibly along with an
-error message generated by your CGI program. In this case, you will
-want to check each of the below sections to see what might be preventing
-your CGI program from emitting the proper HTTP headers.</dd>
-</dl>
-
-
-<h3><a name="filepermissions">File permissions</a></h3>
-
-<p>Remember that the server does not run as you. That is, when the
-server starts up, it is running with the permissions of an unprivileged
-user - usually ``nobody'', or ``www'' - and so it will need extra
-permissions to execute files that are owned by you. Usually, the way to
-give a file sufficient permissions to be executed by ``nobody'' is to
-give everyone execute permission on the file:</p>
-
-<pre>
- chmod a+x first.pl
-</pre>
-
-<p>Also, if your program reads from, or writes to, any other files,
-those files will need to have the correct permissions to permit
-this.</p>
-
-<p>The exception to this is when the server is configured to use <a
-href="../suexec.html">suexec</a>. This program allows CGI programs to
-be run under different user permissions, depending on which virtual
-host or user home directory they are located in. Suexec has very
-strict permission checking, and any failure in that checking will
-result in your CGI programs failing with an "Internal Server Error".
-In this case, you will need to check the suexec log file to see what
-specific security check is failing.</p>
-
-<h3><a name="pathinformation">Path information</a></h3>
-
-<p>When you run a program from your command line, you have certain
-information that is passed to the shell without you thinking about it.
-For example, you have a path, which tells the shell where it can look
-for files that you reference.</p>
-
-<p>When a program runs through the web server as a CGI program, it does
-not have that path. Any programs that you invoke in your CGI program
-(like 'sendmail', for example) will need to be specified by a full
-path, so that the shell can find them when it attempts to execute your
-CGI program.</p>
-
-<p>A common manifestation of this is the path to the script interpreter
-(often <code>perl</code>) indicated in the first line of your CGI
-program, which will look something like:</p>
-
-<pre>
- #!/usr/bin/perl
-</pre>
-
-<p>Make sure that this is in fact the path to the interpreter.</p>
-
-<h3><a name="syntaxerrors">Syntax errors</a></h3>
-
-<p>Most of the time when a CGI program fails, it's because of a problem
-with the program itself. This is particularly true once you get the
-hang of this CGI stuff, and no longer make the above two mistakes.
-Always attempt to run your program from the command line before you
-test if via a browser. This will eliminate most of your problems.</p>
-
-<h3><a name="errorlogs">Error logs</a></h3>
-
-<p>The error logs are your friend. Anything that goes wrong generates
-message in the error log. You should always look there first. If the
-place where you are hosting your web site does not permit you access to
-the error log, you should probably host your site somewhere else. Learn
-to read the error logs, and you'll find that almost all of your
-problems are quickly identified, and quickly solved.</p>
-
-<hr>
-<h2><a name="whatsgoingonbehindthescenes">What's going on behind
-the scenes?</a></h2>
-
-<p>As you become more advanced in CGI programming, it will become
-useful to understand more about what's happening behind the scenes.
-Specifically, how the browser and server communicate with one another.
-Because although it's all very well to write a program that prints
-``Hello, World.'', it's not particularly useful.</p>
-
-<h3><a name="environmentvariables">Environment variables</a></h3>
-
-<p>Environment variables are values that float around you as you use
-your computer. They are useful things like your path (where the
-computer searches for a the actual file implementing a command when you
-type it), your username, your terminal type, and so on. For a full list
-of your normal, every day environment variables, type <code>env</code>
-at a command prompt.</p>
-
-<p>During the CGI transaction, the server and the browser also set
-environment variables, so that they can communicate with one another.
-These are things like the browser type (Netscape, IE, Lynx), the server
-type (Apache, IIS, WebSite), the name of the CGI program that is being
-run, and so on.</p>
-
-<p>These variables are available to the CGI programmer, and are half of
-the story of the client-server communication. The complete list of
-required variables is at <a href=
-"http://hoohoo.ncsa.uiuc.edu/cgi/env.html">http://hoohoo.ncsa.uiuc.edu/cgi/env.html</a></p>
-
-<p>This simple Perl CGI program will display all of the environment
-variables that are being passed around. Two similar programs are
-included in the <code>cgi-bin</code> directory of the Apache
-distribution. Note that some variables are required, while others are
-optional, so you may see some variables listed that were not in the
-official list. In addition, Apache provides many different ways for
-you to <a href="../env.html">add your own environment variables</a> to
-the basic ones provided by default.</p>
-
-<pre>
- #!/usr/bin/perl
- print "Content-type: text/html\n\n";
- foreach $key (keys %ENV) {
- print "$key --> $ENV{$key}<br>";
- }
-</pre>
-
-<h3><a name="stdinandstdout">STDIN and STDOUT</a></h3>
-
-<p>Other communication between the server and the client happens over
-standard input (<code>STDIN</code>) and standard output
-(<code>STDOUT</code>). In normal everyday context, <code>STDIN</code>
-means the keyboard, or a file that a program is given to act on, and
-<code>STDOUT</code> usually means the console or screen.</p>
-
-<p>When you <code>POST</code> a web form to a CGI program, the data in
-that form is bundled up into a special format and gets delivered to
-your CGI program over <code>STDIN</code>. The program then can process
-that data as though it was coming in from the keyboard, or from a
-file</p>
-
-<p>The ``special format'' is very simple. A field name and its value
-are joined together with an equals (=) sign, and pairs of values are
-joined together with an ampersand (&). Inconvenient characters like
-spaces, ampersands, and equals signs, are converted into their hex
-equivalent so that they don't gum up the works. The whole data string
-might look something like:</p>
-
-<pre>
- name=Rich%20Bowen&city=Lexington&state=KY&sidekick=Squirrel%20Monkey
-</pre>
-
-<p>You'll sometimes also see this type of string appended to the a URL.
-When that is done, the server puts that string into the environment
-variable called <code>QUERY_STRING</code>. That's called a
-<code>GET</code> request. Your HTML form specifies whether a
-<code>GET</code> or a <code>POST</code> is used to deliver the data, by
-setting the <code>METHOD</code> attribute in the <code>FORM</code>
-tag.</p>
-
-<p>Your program is then responsible for splitting that string up into
-useful information. Fortunately, there are libraries and modules
-available to help you process this data, as well as handle other of the
-aspects of your CGI program.</p>
-
-<hr>
-<h2><a name="cgimoduleslibraries">CGI modules/libraries</a></h2>
-
-<p>When you write CGI programs, you should consider using a code
-library, or module, to do most of the grunt work for you. This leads to
-fewer errors, and faster development.</p>
-
-<p>If you're writing CGI programs in Perl, modules are available on <a
-href="http://www.cpan.org/">CPAN</a>. The most popular module for this
-purpose is CGI.pm. You might also consider CGI::Lite, which implements
-a minimal set of functionality, which is all you need in most
-programs.</p>
-
-<p>If you're writing CGI programs in C, there are a variety of options.
-One of these is the CGIC library, from <a href=
-"http://www.boutell.com/cgic/">http://www.boutell.com/cgic/</a></p>
-
-<hr>
-<h2><a name="formoreinformation">For more information</a></h2>
-
-<p>There are a large number of CGI resources on the web. You can
-discuss CGI problems with other users on the Usenet group
-comp.infosystems.www.authoring.cgi. And the -servers mailing list from
-the HTML Writers Guild is a great source of answers to your questions.
-You can find out more at <a href=
-"http://www.hwg.org/lists/hwg-servers/">http://www.hwg.org/lists/hwg-servers/</a></p>
-
-<p>And, of course, you should probably read the CGI specification,
-which has all the details on the operation of CGI programs. You can
-find the original version at the <a href=
-"http://hoohoo.ncsa.uiuc.edu/cgi/interface.html">NCSA</a> and there is
-an updated draft at the <a
-href="http://web.golux.com/coar/cgi/">Common Gateway Interface RFC
-project</a>.</p>
-
-<p>When you post a question about a CGI problem that you're having,
-whether to a mailing list, or to a newsgroup, make sure you provide
-enough information about what happened, what you expected to happen,
-and how what actually happened was different, what server you're
-running, what language your CGI program was in, and, if possible, the
-offending code. This will make finding your problem much simpler.</p>
-
-<p>Note that questions about CGI problems should <strong>never</strong>
-be posted to the Apache bug database unless you are sure you have found
-a problem in the Apache source code.</p>
