Windows Phone 7 – WebRequest Caching Nightmare

After a three day long search which instance will cache our REST calls, I found out at this weekend that the Windows Phone 7 client caches our REST calls which we make with the WebRequest class. Because I found no documentation about this fact, I decided to wrote this short hint. Hope I could help anybody with the same inexplicably caching behaviour of the Windows Phone 7 WebRequest calls.

To solve this, I have now added a additional Guid parameter for each call to make them unambiguously.
