CGI

Common Gateway Interface (CGI) programs run on the server and generate a

response to return to the requesting client. CGI programs can be written in various

languages, including C, C++, Java™, Perl™, and as shell scripts. CGI programs are

invoked throughURL invocation.

Enterprise Server complies with the version 1.1 CGI specification.

Sincetheserverstarts upa process each timetheCGIscript or programruns,thisis

an expensive method of programming the server.

Enabling CGI

Enterprise Server provides two ways to identify CGI programs:

• Specifying CGI Directories. The server treats all files in CGI directories as CGI

programs.

• Specifying CGI File Extensions. The server treats all files with the specified

extensions as CGI programs.

Specifying CGI Directories

To specify directories that contain CGI programs (and only CGI programs) use the

CGI Directory page in the Programs tab of the Class Manager. The server treats all

filesinthesedirectoriesasCGIprograms.

For each CGI directory, the file

obj.conf contains a NameTrans directive that

associates the name

cgi with each request for a resource in that directory. These

directives are automatically added to

obj.conf when you specify CGI directories

in the Class Manager interface, or you can manually add them to

obj.conf if

desired.

For example, the following instruction interprets all requests for resources in

http://server-name/cgi-local as requeststoinvokeCGIprogramsinthedirectory

C:/netscape/servers/docs/mycgi.

NameTrans fn="pfx2dir" from="/cgi-local"

dir="C:/netscape/servers/docs/mycgi" name="cgi"

The obj.conf file must contain the following named object:

ObjectType fn="force-type" type="magnus-internal/cgi"

Service fn="send-cgi"

</Object>
