Program Access Restrictions
Program Access Restrictions
You can disable access to CGI programs in certain server areas by using the Deny
command in a Region directive. For example, the directive
Region /~*.cgi* {
Deny
}
denies access to all CGI programs located in user directories, that is, any directory
accessed by a URL beginning with a forward slash followed by a tilde (
/~).
Passing CGI Environment Variables
You use environment variables to pass descriptive information about the server and the
current request to a CGI program. Some of these variables are set for all requests; others
are set only for particular requests. Passing environment variables is described in the
following three tables:
•
Table 8-1 lists and describes the standard environment variables applicable to
generic and Pathway CGI programs.
•
Table 8-2 on page 8-17 lists and describes additional environment variables available
in the iTP Secure WebServer environment.
•
Table 8-3 on page 8-20 tells how to use environment variables from specific
programming languages.
The SSL environment variables apply only to secure versions of the iTP Secure
WebServer.
