[Python-au] help debugging cacheability.py

[David Lutz]

Hello, I'm trying to get the cacheability script from 
http://www.mnot.net/cacheability/download.html working with python 2.3.4

It works fine with python 1.5.2

Here's two test URLs to demonstrate the problem:

Traceback (most recent call last):
   File "./cacheability.py", line 994, in ?

     print f

     return self.__dict__[attr]

I'm guessing that one of the headers that IIS is sending is breaking the 
script?   But not in an old version of python.

Any suggestions as to where I should be looking to fix it?
Thanks.  David.
