Topic: Apachi CGI interface to third party exe

[jonny]

I am creating a web product for a company that already has developed a desktop product written in a proprietary software language, and have come to the conclusion that the fasted way to get the product out the door is to use the code the already exists in the third party language and interface apache with the executable through CGI. Someone has already done this in this language but the source is protected and not redistributable by any means.

I am new to defining apache script processors. I am familiar with how to define them:

Apache config -

#
# Pvx as a script processor
#
ScriptAliasMatch \.pvw /var/www/cgi-bin/pxp.cgi

CGI Script -

#!"C:\Program Files\...\...\pvx.exe" *plus/apache/pxp_cgi -arg arguments here.

What I do not understand at this point is the way that I will communicate back with apache. Basically I need to pass it text that contains JSON responses. The only explanation I have come across is to write to temporary text files on the drive which seems inefficient. Any help or explanation would be greatly appreciated.

well when apache calls the CGI executable
it write the content of the file - the first line to the STDIN of the executable
It then waits for the STDOUT reply of the application. Or times out if it isn't send
