Should it be possible to send a plain, single http POST request (not chunk-encoded), in more than one segment?  I was thinking of using httplib.HTTPConnection and calling the send method more than once (and calling read on the response object after each send).
(Context: I'm collaborating to the design of a server that offers services analogous to transactions [series of interrelated requests-responses]. I'm looking for the simplest, most compatible HTTP representation.)
After being convinced by friends that this should be possible, I found a way to do it.  I override httplib.HTTPResponse (n.b. httplib.HTTPConnection is nice enough to let you specify the response_class it will instantiate).
Looking at socket.py and httplib.py (especially _fileobject.read()), I had noticed that read() only allowed 2 things:

read an exact number of bytes (this returns immediately, even if the connection is not closed)
read all bytes until the connection is closed

I was able to extend this behavior and allow free streaming with just a few lines of code.  I also had to set the will_close member of my HTTPResponse to 0.
I'd still be interested to hear if this is considered acceptable or abusive usage of HTTP.
multiple send on httplib.HTTPConnection, and multiple read on HTTPResponse?
