This did work and I still do have the Runtime mapping thing; wonder what
happened..

If I do iisreset and restart the site, it tends to get over it...

Sometimes getting over it means bugging, now I got
 'module' object has no attribute 'wsgi' 
 Line 14: import django.core.handlers.wsgi
 Line 15: 
 Line 16: application = django.core.handlers.wsgi.WSGIHandler()


 Source File: C:\Program Files\IronPython 2.6\Lib\site-packages\mysite\hello.wsgi    Line: 16 

Then if I edit Web.config, like add a newline, and reload without iisreset or
restart, I get all sorts of funky effects like
http://ironpython.pastebin.com/m757a631b

Is the XML extremely sensitive to newlines and stuff?

The ONLY pattern I've been able to discern is that:
1. requests sometimes take a LONG time, especially the first time around
2. if I reload in mid-request, I might get different effects

The first time it was unset, so it defaulted to
django.contrib.sessions.backends.db

Then I set it explicitly and it still failed.

But like I said above, this tends to break in such random ways,
I think there's something else going on.

Am I the only guy looking at this?

Are there any better traces that can be captured?

I also put this up
http://ironpython.pastebin.com/mf52b185

Hope any of this helps..?

Thanks!
