As of yet, this is my first gripe with POE (or more specifically, POE::Wheel::ReadWrite (not sure which is to blame). Within the server, I need to grab pages from the net. Some of these pages may take quite a number of seconds to retrieve, so I wish to let the user know that it is grabbing the page and that it might take a few seconds. So I programmed the following lines of code, thinking it might just DWIM: 

$heap->{wheel}->put("Grabbing webpage. May take a moment...");

my $ua = new LWP::UserAgent;
my $html = $ua->get($url_to_retrieve);

But of course not! It would make things way too easy for put() to _immediately_ send out the message. So of course, put() places the message in a queue and unfortunately for me, it's not sent out until after the webpage retrieval is complete. Definitely not what I wanted to happen.

I've tried playing with POE::Kernel's delay(), yield() and call() methods, with no working results. If anyone happens to know of some code to help me (or better yet, point me to some docs that I overlooked) I'd be very happy :)
