[mod_python] How to stop PSP Page Cache

Hello, I am using mod_python 3.1.4, and doing psp development. The 
pages work fine without any probelms. However, when I change the psp 
page on disk the changes are not reflected on the version that is 
served to client. I am not caching pages at the browser side.

However restarting the apache server results in correct page being 
served. Is there a way to tell psp handler not to cache the pages?

thanks
Asif
