Gateways are programs which handle information requests and return the appropriate document or generate a document on the fly.
HTTP Servers often allocate special URLs for specific types of files. The most important one is /cgi-bin. This is used to reference the `server scripts' directory -- this is the directory that contains scripts and programs that can be accessed from the browsers, via an HREF. For example, to access the script `phone' (which scans a phonebook for particular names) on the machine `www.foo.com' via http, the HREF is
HREF="http://www.foo.com/cgi-bin/phone"
The URL to access the UCI-NACS' Zot-Dispatch form handling script is
HREF="/cgi-bin/zd.cgi"Here are some references to gateway packages.
