Refer to the Sun Java System Web Server 7.0 CLI Reference Manual for more information on these subcommands.

3 CGI Sec none none urity Con guration (UNIX only). On UNIX/Linux s ystems, Web Server creates and uses a pool of Cgistub processes to execute CGI programs. The use of a Cgistub process to execute CGI programs enables Web Server to create a custom execution environment for CGI programs. For example, using Web Server you can prevent a virtual server s CGI programs from interfering with other users by con guring the CGI programs to be executed with the permissions of a unique UNIX user and group.

The additional security restrictions enforced by Cgistub makes it dif cult for hackers to exploit the CGI subsystem in Web Server 7.0 to get root access. Refer to the section titled Creating Custom Execution Environments for CGI Programs in the Sun Java System Web Server 7.

. Example 9.1 Excerpt from the server.xml File <cgi> < none for none ;cgistub-idle-timeout>60</cgistub-idle-timeout> <max-cgistubs>10</max-cgistubs> <env-variable> <name>MYVAR</name> <value>foo</value> <description>A custom CGI environment variable</description> </env-variable> </cgi>. The server must be restarted to propagate changes made to global CGI settings. The global CGI settings are con gured from the CGI subtab of the Performance tab of a con guration, as shown in Figure 9.12.

These settings can also be manipulated if you use the create-cgi-envvar, deletecgi-envvar, list-cgi-envvars, get-cgi-prop, and set-cgi-prop subcommands of wadm. Refer to the Sun Java System Web Server 7.0 CLI Reference Manual for more information on these subcommands.

The CGI engine in Web Server participates in request processing by using Server Application Functions. 6, Web Server 7.0 Request Processing, describes the different stages of request processing that the Web Server goes through on every request.

Table 9.2 describes the Server Application Functions (SAFs) that implement support for executing CGI programs in Web Server..

9.1 COMMON GATE none for none WAY INTERFACE (CGI). Table 9.2 CGI Server Application Functions Request Processing Stage SAF Init Service init-cgi send-cgi send-wincgi send-shellcgi query-handler Description Con gures the C GI subsystem. This SAF is deprecated and is superseded by the cgi element in the server.xml le.

The send-cgi function sets up the CGI environment variables that are used to pass data to the CGI program, executes the CGI program in a separate process, and sends the results to the client. Parameters to this SAF are used to con gure the custom execution environment for CGI programs on UNIX/Linux systems. You can con gure Web Server to execute a le as a CGI program by associating the le extension with the magnus-internal/cgi MIME type.

The send-wincgi SAF executes the le as a Windows CGI program and sends the results to the client. You can con gure Web Server to execute a le as a Windows CGI program by associating the le extension with the magnus-internal/wincgi MIME type. The send-shellcgi SAF executes the le as a CGI program, using the le associations set in Windows.

The query-handler SAF runs a CGI program and is used to support the obsolete ISINDEX tag. Query handlers are no longer used. Web browsers use HTML forms to submit data to the server.

. Example 9.2 dem none for none onstrates the obj.conf le for a server con guration on Windows that can execute CGI programs.
