Streaming a PUT request

What steps will reproduce the problem?
1. send a big file (more then 100mb) with a PUT request (using python requests 
module)

What is the expected output? What do you see instead?

expected is that the file will find it's merry way into the webdav server

What version of the product are you using? On what operating system?
I'm using python2.7 on winXP

Please provide any additional information below.

this is the log + backtrace:

----------------------------------------

my guess is that PyWebDev is trying to read all the 132463603 byte in one recv, 
which isn't possible.

files that big should be streamed, chunk by chunk.

after fiddling with the code, I've found out I need to setup the server to 
HTTP1.1, which wasn't clear and wasn't on the command line options...

when I turn it on I got this trace back on any file I tried PUTting:

    raise DAV_Error, 424

----------------------------------------

after  adding some debug I found out the _readChunkedData is actually using 
http://en.wikipedia.org/wiki/Chunked_transfer_encoding

isn't there anther way of streaming big files into PyWebDAV ?
