Common Gateway Interface

The Common Gateway Interface (CGI) is a World Wide Web Consortium (w3c.org) standard protocol (RFC3986) for URLs to be processed by a program on the server, rather than to return a static Web page containing fixed HTML content. URLs that include a query string that starts with a ? typically use this format.

Like other URLs, the query parameters are encoded by changing spaces to a single + character, and encoding special characters using URL encoding, often called percent-encoding.

PRPC accepts URLs in the CGI format for:

• The SnapStart desktop interface
• Service HTTP requests (Rule-Service-HTTP rule type)
• Browser requests, such as those from the URL JSP tag

For example, this URL contains a query string:

http://host:8080/prweb/               
    ?pzAuth=guest&[email protected]
    &Password=emV1cw%3D%3D                      
    &pyActivity=AcmeCorp.ComputeVol               
    &Length=1234&width=75&Name=Maximus          

When executed, this URL creates a requestor session, attempts authentication using the user identifier and password provided, places properties named Length, Width, and Name on the clipboard, and starts the activity named AcmeCorp.ComputeVol.
