ap_rwrite and timeout
Hello,
I am writing a module for Apache 2.0.59 that works like a proxy to
expose a Dime Soap Web service over classical HTTP
The problem is when i send the content to the client, if the client
closes the connection or pauses the download, i have to wait the
timeout to detect the problem
The timeout is the Timeout directive of the server, is it possible to
use a shorter timeout for my module ? or having something like
ap_hard_time_out() ?
or how to use a function like poll with a request_rec ? to detect if
the client is ready to receive a packet
Marc

The thing with the timeout is that it's the time for the ACK to come
back from the client. The packet could be written to a DROP firewall
rule, or anything really. If a ICMP port unreach, or ICMP host unreach
comes in response then the timeout, in effect, should be triggered
automatically as the socket will be closed.

I think the ap functions handle this internally, so I don't know how
you would hook into those things.
This probably doesn't answer your question, generally, the application
does not deal with socket issues. If you wish to kill off the socket,
you might find looking for the file descriptor, or socket handle via
the source address and source port helpful, to then write a FIN/RST or
close it. But this is probably random land and I advise that you don't
give up too much time on this track.
