When you say 'Apache::Registry' script, are you using the 
'oi2.cgi' script that comes along with your website? If so, 
that's very interesting -- I've never tried that :-)

Since the oi2.cgi script and the handler use the same modules I 
don't think that would be the problem. I assume you're still 
using the:

   PerlRequire /path/to/mysite/conf/startup.pl

which does most of the necessary 'use' and 'require' at server 
startup time. That should do the same work for both 
Apache::Registry and using the handler.

So I would guess the difference occurs because the handler stores 
additional data between requests -- oi2.cgi recreates the context 
object every time the script is called. Although since it's 
storing the singleton Context object in a class variable it might 
be maintained across requests...

Honestly, I've only used Apache::Registry to run a TWiki site so 
I'm not sure what all the tips and tricks are, what it does 
behind the scenes, etc. I think there are Apache:: modules you 
can use to peek into what objects are stored between requests, 
how big they are, etc. That would probably be your next step.

Hope that makes sense,

Chris
