Stan - I don't have an acs 3.x version installed but with the 4.x stuff
the 404 is still being sent out by ns_returnnotfound
(which internally calls Ns_ConnRedirect to restart handling at the rp_handler).
It isn't clear to me why 3.x 404 return would not just work).
The only difference between what 4.x does and ns_sourceproc does is
that ns_sourceproc calls ns_returnnotfound with a $conn arg.
The fix I made was entirely a 4.x change and no I did not have to touch
ns_sourceproc (although the request processer only calls ns_sourceproc
if it knows the file exists and does it's own ns_returnnotfound if it does not).
Gilbert - I think it's more likely the bug you saw would be an AOLServer
bug since once you get the recursion limit error very little oacs code
gets run. It is concievable it is trace filter problem
and you might try putting debug statements in any you have running.
Also, I did probably 50 404 gets without seeing the server hang
and I get lots of hits from code red etal and those do not seem to
hang the server either.
