In apache 2.2 / mod_perl2 I'd like to add a translation phase handler (PerlTransHandler) but have it run after mod_rewrite. In apache 1.3 this was done by controlling module load order.

Does the memory get released when I throw an exception?

Hi, I was debating with some colleges about what happens when you throw an exception in a dynamically allocated class. I know that malloc gets called, and then the constructor of the class.

Vectored exception handler and Microsoft C runtime error handling

Hi, I've recently implemented some vectored exception handling to catch errors in our software. This is especially useful as we've just converted from vc6 to vs2005.
