HTTP server in POE with a twist

Hi,

I need to write a HTTP server that interacts with XMPP, using POE.

The problem is that after a HTTP request, I have to do some XMPP  
transactions and only after that I can generate the response.
From the PoCo::Server::HTTP docs, I don't seem to be able to put a  
request on hold, do some other stuff, and then generate the response,  
correct?
Anybody done something like this before?

Thanks,
