By using a PerlAccessHandler, you are adding a step into the standard
apache process.

So:
 - the user goes to: /path/file.xyz
 - your access handler performs its checks
 - Allowed? 
   - Y : 
     - return OK
     - file served by standard apache means
   - N : 
     - return DENY
     - apache sends a 403 (or whatever) response

All you are doing is replacing (or adding to) mod_access - your module
works in exactly the same way.

Also, you could use your handler at the same time as mod_access, so you
could (eg) use mod_access to check IP addresses, and your handler to
check something else, if you like.
