how to share data among modperl processes

[Foo Ji-Haw]

Hi all,   I have a simple need where a process can take minutes to complete. But I want to display some progress bar of sorts to the user.   My idea is to have the handler call the local url which does the heavy lifting. Something like this: http://localhost/job/dojob => launches => http://localhost/job/actualjobworker     The local url will set some global hash to say that it is still working on the job. The original handler (/job/dojob) becomes a polling script to check on the global hash to see if the work is completed.   I read from the wiki that it is possible to have a 'global' variable where all process can read/write to it. Can someone point me in the direction? I tried perl.apache.org but can't find anything there. A url should do the trick.   Thanks.
