Hi..I would really appreciate if some one can help me with caching in C#....Please please help me....

Probably, you mean this: http://msdn.microsoft.com/en-us/library/ff383731%28v=azure.10%29.aspx[^].

If so, you can get familiar with these matters if you start learning using original MDSN documentation from the page referenced above. Or even earlier: here:

or even here: http://msdn.microsoft.com/en-us/library/ff361664%28v=vs.110%29.aspx[^].
