"Newbie" questions are welcome, at least until the list gets busy enough to split into developer and user tracks. There currently is no way to shut down a streaming request. I could see where it's needed for halting a streamed media download. You can probably work around this by sending a signal to the HTTP component, like: $_[KERNEL]->signal( ua => 'KILL' ); That should just kill off the component entirely, though. Any parallel requests would also be aborted, and you'd need to create a new POE::Component::Client::HTTP if you wanted to run more requests. This message has been Cc'd to bug-POE-Component-Client-HTTP@rt.cpan.org so I'll remember that the feature's needed. -- Rocco Caputo - rcaputo@pobox.com - http://poe.perl.org/

it would also be good if Streaming responses could also respect MaxSize. that would help in the case where you want to avoid storing a large file in memory and stream it directly to disk. On Wed Feb 11 12:58:31 2004, rcaputo@pobox.com wrote: Show quoted text

can't you just use the recipe listed in the cookbook (insider HTTP, not user code): http://poe.perl.org/?Poe_cookbook/graceful_wheel_shutdown

That doesn't work here because the interface for POE::Wheel::* is different from the interfaces for POE::Component::*.

Added a "cancel" command that takes a single HTTP::Request object. Committed the fix as revision 260. Uploaded version 0.76 to PAUSE. Thanks for your request!
