[mod_python] Re: Strange HTTP Response

I think we finally resolved the problem -- sort of.

We were using the util.redirect.  However, the problem went away after
replacing it with these two lines:

req.headers_out['Location'] = newPath

The primary difference between, the two methods is that util.redirect
uses a 302 and HTTP_TEMPORARY_REDIRECT returns a 307 response code.

The only problem is that IE on Mac doesn't seem to like 307 response
codes.  We're sticking with this for the time being.  However, does
anyone have any thoughts on what's causing this?  302 shouldn't be
causing these kinds of problems, no?

If you want to see the problem/solution first hand, here's the URL: 

If anyone has any thoughts, we'd really appreciate it.
