Thanks Bill for the reply.

My 2 cents (I am filter novice :) )

I observed one more thing :  Filters such as http_header_filter removes itself from filter
chain by calling "ap_remove_output_filter". So  this filter should take care that if I am
sending 1xx kind of responses it should not remove it from chain, else in subsequent responses
there are no headers.

Actually it will become necessary when mod_dav will be pushed more into commercial arena.
COPYing large collection etc are normal operations and often clients sets time-out of 120sec
or so. Its necessary from UI perspective (could show progress bar etc.).

I hope there would be more cleaner way of doing it somewhere in future. :)

Thanks a lot
