RE: mod_perl problems

[Harikrishnan B. <har...@jp...>]

Check the error_log of apache and you might get some hints
on why apache gives the error. Always check the errorlog.

(Guess #1)
CGI and mod_perl environments are not exactly the same.
I have seen problems if my script is 'forking' and=20
invoking another script (even indirectly). STDIN and STDOUT
file descriptors are messed up in mod_perl 1.26. So
open("|...") would also fail under mod_perl.=20

(Guess #2)
mod_perl doesn't add the standard HTTP headers unless you
have SendHeaders option ( I forget the exact name - check
mod_perl documentation). What this means is that you
script would have to print *all* HTTP headers in addition
to printing the Content-Type and so on.. This includes the
HTTP status line. Whenever apache detects that some response
doesn't have adequate headers, it will prints "internal server
error".
