[mapserver-users] My gis program

[woodbri at swoodbridge.com]

Puneet et al,

Yes, it is possible to run as an apache module, but if you start 
getting multiple hits you run the risk of one process trashing the 
data of another. I never ran into a problem when I originally had PHP 
built as an apache module, but then I was the only user :)

I know a lot of work has been done regarding thread safety, but I 
don't think all of the issues have be resolved or if the developer 
even know what they all might be. This makes it extremely risky for a 
production environment.

YMMV,
