[CS-FSLUG] FastCGI

[Timothy Butler]

Thanks, Micah. That’s what I was thinking. There’s apparently something like Python’s WSGI called PSGI, but so far I’ve found it easier to figure out how to implement FastCGI — it’s dead simple so far.

One thing I’ve found conflicting info on that maybe you have a thought on, since it applies across languages, I believe: some people say you should never call exit() on a script being run through FastCGI. Others say it doesn’t matter. My code uses exit in a lot of places where it is important to make sure nothing keeps executing, but there’s not a fatal error. I’ve mostly used it so that I don’t accidentally overlook something continuing on and cause a security hole. However, I’m wondering if I need to remove those calls. 

I found one suggestion of using GOTO (which I’ve not used since I played with Basic so many years ago) to go to an empty block of code beyond all the other code as a replacement to exit(). 

Any thoughts?

Tim

My CMS goes from taking around 600ms to fulfill a request to as low as 180ms (all but as fast as a static page). So far as I can tell, it has several advantages over mod_perl, most importantly that it works with Suexec to keep scripts from running with privileges beyond the current site’s own.
