Configuring Apache to permit CGI 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. Note: If Apache has been built with shared module support you need to ensure that the module is loaded; in your httpd.conf you need to make sure the LoadModule directive has not been commented out. A correctly configured directive may look like this: LoadModule cgid_module modules/mod_cgid.so On Windows, or using a non-threaded MPM like prefork, A correctly configured directive may look like this: LoadModule cgi_module modules/mod_cgi.so ScriptAlias The ScriptAlias 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. The ScriptAlias directive looks like: ScriptAlias "/cgi-bin/" "/usr/local/apache2/cgi-bin/" The example shown is from your default httpd.conf configuration file, if you installed Apache in the default location. The ScriptAlias directive is much like the Alias directive, which defines a URL prefix that is to mapped to a particular directory. Alias and ScriptAlias are usually used for direc

For the purposes of this article, I am assuming that your CGI script is a http://www.thesitewizard.com/archive/servererror.shtml Perl script, by far the most commonly available on the Internet. We will try to eliminate the most common errors first (and the easiest-to-eliminate ones): Location Did you upload your scripts into the right place? This is not as obvious as it may seem. Some servers are configured to run your CGI scripts anywhere. Others will only run it when it is installed in a particular directory. It is not just a matter of creating a "cgi-bin" directory — for example, some hosts configure the server so that it will run scripts only from a particular directory outside the web directory structure (for security reasons). Your web page will still call the script "/cgi-bin/script.pl" but the server maps it to the actual directory. You will have to upload it in the right directory, regardless of what your web page calls it. Find out such information from your web host's documentation.

From RFC 2616 (emphasis my own): Request (section 5) and Response (section 6) messages use the generic message format of RFC 822 [9] for transferring entities (the payload of the message). Both types of message consist of a start-line, zero or more header fields (also known as "headers"), an empty line (i.e., a line with nothing preceding the CRLF) indicating the end of the header fields, and possibly a message-body. To fix the problem, put another echo before echo "", so that the headers are clearly separated from the body. share|improve this answer answered Apr 9 '14 at 8:13 Chris Down 55.8k7132166 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Em
