finding "context" in mod_perl handler

[André Warnier <aw...@ice-sa.com>]

Hi.

Supposing I have this kind of setup

<Location /xyz>
   PerlAuthenhandler My::AuthModule
   ...
</Location>

...

<Directory /var/www/some/path>
   PerlAuthenhandler My::AuthModule
   ...
</Directory>

and a request is made for "/xyz", and as a result the module is called,

is there some way in My::AuthModule::handler(), by which I can find out 
that, in *this* instance, I am being called in the "context" of the 
<Location> directive above, as opposed to the <Directory> case ?

I mean, I could do something like respectively
   PerlSetVar context "location:/xyz"
and
   PerlSetVar context "dir:/some/path"

and then check the var in the handler, but there has to be a 
better/cleaner way, no ?

Thanks
André

Just get the info from the request object within the handler?

The first thing i'd try is checking $r->location.  I'm not sure what 
that does for the Directory instance, but in the Location instance it'll 
return '/xyz'.  I don't know of a comparable way to do the same thing 
with Directory directives.

Assuming of course that you care about Directory xyz vs Location xyz.
If they're totally different URLs, then checking the location is all
you need.

That's what I would do.  Easy and foolproof.
