Cache on PPC Device

[victor]

Hello,

Made an app for a PDA; it gets an image via HTTPWebRequest and
HTTPWebResponse.
All runs well on the PPC Emulator, but on the PDA it only gets the
image once. A repeated request does not produce another image.
A same request via the IE URL-bar works fine, so it can't be a caching
matter. What am I doing wrong?
Victor.

Can you post a code snippet? Are you closing the returned webresponses
