[mod_python] how do i share variables accross requests?

Hi,

Yes, ASP application object is nice, if you would like to cache some data.

I go trought the same problem, and i finally choose the HEAP type table (in
memory) of MySQL to store some strings i need, and do something similar.

This have the advantage to be faster than a disk table, and not dependent of
Apache.

But if mysql is restarted for any reason, you have to recreate table...

I hope this help

You probably have encountered this feature in other application
frameworks... i remember i was using it in ASP, it was called the
Application Object. You could store variables (ints, strings, objects)
in it and every request could read and write them thread-safely. A
simple example using this feature would be a user-online counter.
Every request would check if the session is new. If it is, increment the
counter and register a cleanup function for the session to decrement it.
Now, how do i implement it in python?
global variables, as far as i've understood, are not global to the
server, just to the child process spawned by the server, so they cannot
be used.
Do i really have to pickle what i want to share and write it on disk
using dbm, mysql or such? Wouldn't this be terribly inefficient,
pickiling and unpickling every request?
Does anybody have already implemented something similar and can post the
code?

Thank you
Riccardo
