I haven't found any way to dump the actual headers from within Twisted

The getPage function in twisted.web is suited for simple calls but won't return returns. What you have to do is create your own slightly modified version of getPage that keeps track of the factory used for the call (by attaching it to the deferred or something).

Yah, I kind of think this code was intended to do his own getPage() but I'm not exactly sure what the point was. Maybe he used it for debugging along the way, but the original intent was lost due to lack of VCS (as was he!)

I ended up rewriting it to use the simple client.getPage()

Along the way, I ran into:

Good Lord, no wonder I'm confused.

Half PEP-8, http://www.python.org/dev/peps/pep-0008/, half JavaRama.

I finally figured out that it was a stupid string formatting bug in the code that was being echoed by Twisted but swallowed by the "Grand Catcher of all Things Exception" in Twisted..

Once I found and fixed that, everything works fine -- until the next time.

As Reza Lotun pointed out, exceptions raised by application code and caught by Twisted are logged. If you find a place where application code can raise an exception and Twisted doesn't log it, this is a bug and should be reported. Jean-Paul
