Hi,
I've looked high and low and searched the groups for a solution. I
understand that suexec strips environmental variables before it launches
the child process. Looking at the c code it uses execve(). My question
is: how can I get child processes to inherit some environmental
variables from a central file (like source profilename). I.E. I'd like
to have *one* file that specifies environmental variables for all sorts
of cgi scripts (bash/perl/python/c) etc. Is that possible?

Thanks in advance,
Yi

You can write your own C code into, or in place of, suexec.c (be beware
if you don't know why absolutely everything it does is done, then you
could be exposing your server to exploits). If you can program in C then
there's no reason you can't make it do exactly what _you_ want it to do.
That's one of the reasons for having things in open source. And if you
can't or don't want to do that, I'm sure there are hundreds of people who
(like me) could do it for you for some price.

Modifying the c code is not so tricky, what becomes tricky will be
maintaining apache for future upgrades.
