Mayur,

I do not fully understand how your question refers to wininet technology,
but I will try to answer. Class function can also be hooked just like any
other function.

The only difference between stand-alone function and class function is that
class function retireives from ECX register "this" pointer to access the
data of class, so hooking function should store ecx value before modifying
it and then restore it before passing control to hooked code.

I did not used detour to perform functions hooking - I did it myself, so I
cant suggest you samples, etc. Google for it and you will find what you
need.
