| 10 | <p>The CGI (Common Gateway Interface) defines a way for a web server to
|
| 11 | interact with external content-generating programs, which are often
|
| 12 | referred to as CGI programs or CGI scripts.
|
| 13 | </p>
|
| 14 |
|
| 15 | <p>Within Tomcat, CGI support can be added when you are using Tomcat as your
|
| 16 | HTTP server and require CGI support. Typically this is done
|
| 17 | during development when you don't want to run a web server like
|
| 18 | Apache httpd.
|
| 19 | Tomcat's CGI support is largely compatible with Apache httpd's,
|
| 20 | but there are some limitations (e.g., only one cgi-bin directory).
|
| 21 | </p>
|
| 22 |
|
| 23 | <p>CGI support is implemented using the servlet class
|
| 24 | <code>org.apache.catalina.servlets.CGIServlet</code>. Traditionally,
|
| 25 | this servlet is mapped to the URL pattern "/cgi-bin/*".</p>
|
| 26 |
|
| 27 | <p>By default CGI support is disabled in Tomcat.</p>

| 30 | <p><strong>CAUTION</strong> - CGI scripts are used to execute programs
|
| 31 | external to the Tomcat JVM. If you are using the Java SecurityManager this
|
| 32 | will bypass your security policy configuration in <code>catalina.policy.</code></p>
|
| 33 |
|
| 34 | <p>Remove the XML comments from around the CGI servlet and servlet-mapping
|
| 35 | configuration in <code>$CATALINA_BASE/conf/web.xml</code>.</p>
|
| 36 |
|
| 37 | <p>Only Contexts which are marked as privileged may use the CGI servlet (see the
|
| 38 | privileged property of the Context element).</p>

|
| 42 | <p>There are several servlet init parameters which can be used to
|
| 43 | configure the behaviour of the CGI servlet.
|
| 44 | <ul>
|
| 45 | <li><strong>cgiPathPrefix</strong> - The CGI search path will start at
|
| 46 | the web application root directory + File.separator + this prefix.
|
| 47 | The default cgiPathPrefix is <code>WEB-INF/cgi</code></li>
|
| 48 | <li><strong>debug</strong> - Debugging detail level for messages logged
|
| 49 | by this servlet. Default 0.</li>
|
| 50 | <li><strong>executable</strong> - The of the executable to be used to
|
| 51 | run the script. You may explicitly set this parameter to be an empty string
|
| 52 | if your script is itself executable (e.g. an exe file). Default is
|
| 53 | <code>perl</code>.</li>
|
| 54 | <li><strong>executable-arg-1</strong>, <strong>executable-arg-2</strong>,
|
| 55 | and so on - additional arguments for the executable. These precede the
|
| 56 | CGI script name. By default there are no additional arguments.</li>
|
| 57 | <li><strong>parameterEncoding</strong> - Name of the parameter encoding
|
| 58 | to be used with the CGI servlet. Default is
|
| 59 | <code>System.getProperty("file.encoding","UTF-8")</code>.</li>
|
| 60 | <li><strong>passShellEnvironment</strong> - Should the shell environment
|
| 61 | variables (if any) be passed to the CGI script? Default is
|
| 62 | <code>false</code>.</li>
|
| 63 | <li><strong>stderrTimeout</strong> - The time (in milliseconds) to wait for
|
| 64 | the reading of stderr to complete before terminating the CGI process. Default
|
| 65 | is 2000.</li>
|
| 66 | </ul>
