Caching data and images in wp7

I searched on google for how to do data(xml) and image caching on windows phone 7, but did not find any luck. Please direct me to the right place from where I can read about caching mechanism in wp7. (FYI : I use HttpWebRequest to make request to the server and receive response as xml).

Thanks in advance!

you could use the Isolated Storage to cache both your data & images.

Essentially, you could write key-value pairs or entire files (using byte stream) into the sand-boxed Isolated Storage.

See if the two links below help:
