Hi, following up http://mail.python.org/pipermail/docs/2011-February/003096.html I wrote a patch to introduce the 'Host' header in the HTTP example of asyncore doc. I've also fixed an indentation error with the last 2 lines of the same example (simple cut&paste would fail with "unexpected intentantion").

Given it's a doc issue, and it quite easy, I think it should be backported to the current on-maintainence releases (the example fails on all of them).
