<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.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>Within Tomcat, CGI support can be added when you are using Tomcat as your
|
||
|
|
HTTP server and require CGI support. Typically this is done
|
||
|
|
during development when you don't want to run a web server like
|
||
|
|
Apache httpd.
|
||
|
|
Tomcat's CGI support is largely compatible with Apache httpd's,
|
||
|
|
but there are some limitations (e.g., only one cgi-bin directory).
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>CGI support is implemented using the servlet class
|
||
|
|
<code>org.apache.catalina.servlets.CGIServlet</code>. Traditionally,
|
||
|
|
this servlet is mapped to the URL pattern "/cgi-bin/*".</p>
|
||
|
|
|
||
|
|
<p>By default CGI support is disabled in Tomcat.</p>

<p>There are several servlet init parameters which can be used to
|
||
|
|
configure the behaviour of the CGI servlet.
|
||
|
|
<ul>
|
||
|
|
<li><strong>cgiPathPrefix</strong> - The CGI search path will start at
|
||
|
|
the web application root directory + File.separator + this prefix.
|
||
|
|
The default cgiPathPrefix is <code>WEB-INF/cgi</code></li>
|
||
|
|
<li><strong>debug</strong> - Debugging detail level for messages logged
|
||
|
|
by this servlet. Default 0.</li>
|
||
|
|
<li><strong>executable</strong> - The of the executable to be used to
|
||
|
|
run the script. Default is <code>perl</code>.</li>
|
||
|
|
<li><strong>parameterEncoding</strong> - Name of the parameter encoding
|
||
|
|
to be used with the GCI servlet. Default is
|
||
|
|
<code>System.getProperty("file.encoding","UTF-8")</code>.</li>
|
||
|
|
<li><strong>passShellEnvironment</strong> - Should the shell environment
|
||
|
|
variables (if any) be passed to the CGI script? Default is
|
||
|
|
<code>false</code>.</li>
