extension

[RL Autry]

Hello everyone:

Can anyone tell us where to find a list of all of the extensions used in 
cgi programming.
Such as in this address:    cgi-bin/rightnow.cfg/php/
what would type of Perl file would    *.cfg   be?

We are trying to learn what they are and the individual purposes behind them.

If anyone knows that would be great, we have not been able to find any 
definitive documentation on extensions or their usage.


Thanks,
RL
