Probably your backend doesn't do what you think it does.

Confirming that your ASP backend does something its not
expected to do.

How do you see that?
I suggest you run this request through debug mode and post
the output, or better yet, tcpdump (-s0) the backend traffic
to see if the ASP backend actually returns a valid response (I doubt it).
