 Chris == Chris Thompson [EMAIL PROTECTED]

Chris I've got a hash %s successfully re tied every request. I'm
Chris using it to store a session id and userid with success, so
Chris I know it's storing.

In the Behavior section of the Apache::Session man page, you'll find:

  Note that Apache::Session does only a shallow check to see if
  anything has changed.  If nothing changes in the top level tied
  hash, the data will not be updated in the back- ing store.  You
  are encouraged to timestamp the session hash so that it is sure
  to be updated.

Basically, you'll need to either:

  1. Use the 'timestamp' technique suggested above.

  2. Deference your variables a bit before updates.  Instead of:

   $s{$x}-[$y]-{$z} = 5;

 you'll need to use some intermediate variables:

   $q = $s{$x}-[$y];
   $q-{$z} = 5;
   $s{$x} = $q;

RTFM.

This is documented (Apache::Session doesn't recurse into the data
structure to look for changes) somewhere ...

I use this whenever changing the session to force it to always get written
back to the database:
  tied(%session)-make_modified;
