Also, you may be completely misunderstanding what you have configured.

Once a request starts it must be finished. There are only two ways to
finish requests in HTTP/1.1 and one of those ways is to absorb and
discard any payload that exists on the request message. Which matches
your description perfectly.

We will need to see how you have 'blocked' the traffic and what the
message headers going through contain.
