progress indicator in a mod_python script

[Josh Bloom]

Hi Rajarshi,

What you probably want to do is break this into multiple parts.

When a request comes in to perform a query consider this a new job, give it
an ID and set it off and running.
Then return an HTML page that knows to keep checking a status URL (based on
the ID) every few seconds to see if the job is done, if the job is done,
return the results, if its not return keeps checking until its.

Here's some info about making an HTML Page refresh itself automatically.
