I already had had a loop

for( my $srv=3DApache2::ServerUtil->server; $srv; $srv=3D$srv->next ) {...}

But in the same function I had a variable named $s that also was a server=20
object. Now due to a simple spelling mistake inside the loop I had looked 5=
=20
times at $s instead of $srv wondering why my configuration was undef all th=
e=20
time, ;-).

I think a document explaining the fundamental Apache/mod_perl data structur=
es=20
in terms of C _and_ mod_perl would be good. Then it can be linked from the=
=20
rest of the docs. BTW, is there somewhere a good Apache API documentation?=
=20
All my knowledge about it comes from looking at mod_perl, mod_dir,=20
mod_rewrite, mod_ssl, etc.
