this gives details of the network programming

This directory holds an example of using an ISINDEX HTML tag to 
provide a single line of text as a parameter to a GCI program.
The CGI program greps a dictionary (/usr/dict/words) for the 
string submitted and prints out a list of all matches found.

Files:

isindex.html  - an HTML page that contains the ISINDEX tag.
isindex.c     - the CGI program source code.
runfromshell  - a schell script that sets up some environment variables
	        so the CGI program can be tested from the command line.
