It's a handler registered with  ap_hook_insert_filter(my_insert_filter, 
NULL, NULL, APR_HOOK_MIDDLE);
my_insert_filter adds output filter and calls apreq_request(r, NULL);
Output filter is not called because Apache detects error (400).
Output filter doesn't generate any data. There is no content handler in 
my module.

My module calls apreq_request(r, NULL) from insert_filter handler.
Yesterday mod_apreq.so worked Ok (client received normal responds and
I was able to get request parameters).
But today browsers started getting "400 Bad request". As soon as I
disable mod_apreq.so browser gets normal data.

What's wrong?

It's very hard to say at this point.  You need to provide more
data points for us to make an intelligent guess.

  1) Do the bad requests go away after restarting the server?
