Intercept requests and modification of the server response

[athapa]

I'd think proxy server would be easier than trying to make some other drivers to intercept and modify the packets.

Seems like windivert may let you do what you want. However I've never used that myself. Also it is in c not c#. Not sure if anyone have ported that. You may be able to pinvoke windivert dlls.

The closest thing I've used in c# is winpcap but that only intercept but not modify packets.

HTH,
