Django cisco phonebook

Yesterday I was fooling around with python and trying to serve some XML to a Cisco 7960 I have. I spent a lot of time getting my web server set up to serve a dynamic XML page which I could pop my phone book information into and when I finally got it done it wouldn't work. Searching online I found out that the latest firmwares from Cisco, 9.*, has a couple of bugs in it dealing with XML. Unfortunately I don't remember where I found this information but I can give out the sparks notes on what I saw.

When I was served the page from a web server, if it responded HTTP/1.0 OK, no good, the phone would only accept if it was HTTP/1.1 . I was getting some cryptic 404/BTXML errors but I could see that the files were fine by loading it on to the production server as a static file. Sure enough the phone was able to parse it, so I actually moved the dynamic parts to the production server to see if it would work as well.

After moving it, the phone can read it fine but I am getting some errors that look like encoding problems. I am going to have to look into this some more later, but here is what I have tried so far as well as some notes about my setup which I will release after I get all the problems worked out.

Set the encoding in the <xml ...> tag that prefixes the generated XML for the phone book.

I am using minidom.Document from python to write the XML files and I have noticed that the ends of the strings are mac like, but I don't think this is a problem since apache served the downloaded file to the phone just fine.

This has potential to be very cool, but until it gets worked out, its useless.
