You didn't search the guide, even if you try to make everyone believe that
you did, and starting a thread that was documented long time ago (I'm
talking about using USR2, not the caching technique). The first hit in the
search gives:
http://thingy.kcilink.com/modperlguide/debug/Using_the_Perl_Trace.html
which is exactly what you need.
Your question about reloading something from within the code is answered
here:
http://perl.apache.org/guide/porting.html#Configuration_Files_Writing_Dy
and here:
http://perl.apache.org/guide/porting.html#Using_Apache_Reload
Hope this helps.
