Projektor and Proxy

Howdy …

I have build a small Desktop Application which reads in two RSS Feeds. So far so good. When the Customer installs it, it only reads the Feeds once and when the Application is started the next day it has the same RSS Feed from the day before … They use a Proxy for Internet. So, does any1 know how to avoid this?? Generating a random number (like i do for the internet) wont work as far as i know …

thanx in advance

cheers
