notes() and mod_perl ErrorDocuments

["Hann, Brian" <Br...@umb.com>]

I have a mod_perl handler set as the 401 ErrorDocument for a certain
location that requires authentication.  I would like to store data in
notes() in the first location so that the 401 handler can access them.
Is that possible? So far I haven't been able to get it to work.  If it
is not, is there some way I could internally mimic Apache's
authentication challenge/response setup?  For instance, what happens
when you return AUTH_REQUIRED to Apache?  Is it possible to do this
inside a mod_perl handler by using set_handlers()?
 
Thanks,

this is all explained in chapter 13 in the cookbook, as well as in the eagle 
book.  for an example of plugging into authentication, see

well, not really.  unfortunately, you can't just set or push authentication, 
since Apache skips it unless you have a Require directive attached to the 
ErrorDocument.
