"show ip wccp [service] detail" will explicitly tell you the redirection
method & Hash Assignment method used.
in your case, it has said that the redirect-method is L2 (rather than GRE).
as far the Hash Assignment, if it doesn't mention it, then i can almost
guarantee that you're running XOR Hashing. (that was the only method
available before Mask Assignment appeared).
note that you need 12.1(13)E. ("Mask Assignment" first appeared in
12.1(xx)EX where i think 'xx' was 11, but i could be wrong on the exact
version.)
if you're running 12.1(13)E or later, you'd get something like:
