[ILUG] IPC and CGI

[Dale Dunlea]

Hi All,

I have a CGI script. It's python, but I'm not set in stone on this. 
Anyway, it has to parse a reasonably large, and largely static, file at 
startup before doing its thing. The problem is that the file it must 
parse is likely to grow over time, and will get quite large. Which means 
that parsing it every time the CGI scripts gets run is going to be 
arduous and may become unacceptably slow.

The plan is to write a daemon program of some description that parses 
the file and maintains it, and then have a separate CGI script that 
interrogates this daemon for the specific data it needs when it needs it.

First of all, is this the way to do it, or is there a better method?
Secondly, what's a good way to provide IPC on linux such that the CGI 
script and the daemon can play nice?

Thanks in advance,
Dale.
