OK, here is a working example:

First you need a html page with form(s), lets call it test.html and you put it into the document root of the server:
Code:
<html><head><title>Test Form</title></head>
<body>
  <form action="/cgi-bin/test.cgi" method="get">
    input for GET: <input name="get_input">
    <input type=submit value="Submit via GET">
  </form>
  <form action="/cgi-bin/test.cgi" method="post">
    input for POST: <input name="post_input">
    <input type=submit value="Submit via POST">
  </form>
  </body>
</html>

Next you need a cgi-script. I choose a shellscript using the kornshell. You save it as "test.cgi" into the cgi-bin directory of your webserver.
Code:
#!/bin/ksh
print "Content-type: text/plain\r\n\r"
print "my query string from (GET) is \"$QUERY_STRING\""
print "\nmy stdin (from POST) is"
cat

When you open the test.html page in your browser, you can enter a string into one of the two input fields and press the submit button adjacent to it.

When you press the "Submit via GET" button, you effectively call /cgi-bin/test.cgi?get_input=your_input_string and the browser shows this output:
Code:
my query string from (GET) is "get_input=your_input_string"
my stdin (from POST) is

When you press the "Submit via POST" button, your input is sent to the stdin of the cgi-script.
Code:
my query string from (GET) is ""
my stdin (from POST) is
post_input=your_input_string

What's left for you to do is: receive the actual user's input either via GET or POST and then process the input according to your needs.

I hope, this helps to understand what's going on.

git-instaweb

GIT-INSTAWEB(1) 						    Git Manual							   GIT-INSTAWEB(1)

NAME

       git-instaweb - Instantly browse your working repository in gitweb

SYNOPSIS

       git instaweb [--local] [--httpd=<httpd>] [--port=<port>]
		      [--browser=<browser>]
       git instaweb [--start] [--stop] [--restart]

DESCRIPTION

       A simple script to set up gitweb and a web server for browsing the local repository.

OPTIONS

       -l, --local
	   Only bind the web server to the local IP (127.0.0.1).

       -d, --httpd
	   The HTTP daemon command-line that will be executed. Command-line options may be specified here, and the configuration file will be
	   added at the end of the command-line. Currently apache2, lighttpd, mongoose and webrick are supported. (Default: lighttpd)

       -m, --module-path
	   The module path (only needed if httpd is Apache). (Default: /usr/lib/apache2/modules)

       -p, --port
	   The port number to bind the httpd to. (Default: 1234)

       -b, --browser
	   The web browser that should be used to view the gitweb page. This will be passed to the git web--browse helper script along with the
	   URL of the gitweb instance. See git-web--browse(1) for more information about this. If the script fails, the URL will be printed to
	   stdout.

       --start
	   Start the httpd instance and exit. This does not generate any of the configuration files for spawning a new instance.

       --stop
	   Stop the httpd instance and exit. This does not generate any of the configuration files for spawning a new instance, nor does it close
	   the browser.

       --restart
	   Restart the httpd instance and exit. This does not generate any of the configuration files for spawning a new instance.

CONFIGURATION

       You may specify configuration in your .git/config

	   .ft C
	   [instaweb]
		   local = true
		   httpd = apache2 -f
		   port = 4321
		   browser = konqueror
		   modulepath = /usr/lib/apache2/modules
	   .ft

       If the configuration variable instaweb.browser is not set, web.browser will be used instead if it is defined. See git-web--browse(1) for
       more information about this.
