I just did this yesterday with the 'poster' module after fumbling around with various other ideas, which in the end just produced a lot of code and didn't get me very far. Poster makes this pretty easy, and if you can't install it to the system python path, use 'setup.py install --user' and it'll put it in your home directory under ~/.local. <div>

If you don't need the threading, you should be able to rip the 'run()' method out of the class and just run it by itself (save an edit or two -- like hard-coding or otherwise replacing self.port). </div>

</div> And are you expecting the server to somehow crawl down the socket to<br>
your machine to find the file, then suck it up?<br>
<br>
Where do you actually attach the file data to the outgoing response?<br>
<br>
Suggest you reference the RFC that added file upload to HTML:<br>
<a href="http://www.faqs.org/rfcs/rfc1867.html" target="_blank">http://www.faqs.org/rfcs/rfc1867.html</a><br>
<br>
In particular, section 3.3<br>
-=-=-=-=-=-<br>
3.3 use of multipart/form-data<br>
<br>
The definition of multipart/form-data is included in section 7. A<br>
boundary is selected that does not occur in any of the data. (This<br>
selection is sometimes done probabilisticly.) Each field of the form<br>
is sent, in the order in which it occurs in the form, as a part of<br>
the multipart stream. Each part identifies the INPUT name within the<br>
original HTML form. Each part should be labelled with an appropriate<br>
content-type if the media type is known (e.g., inferred from the file<br>
extension or operating system typing information) or as<br>
application/octet-stream.<br>
-=-=-=-=-=-<br>
<br>
You've just supplied the file NAME part of the form, but not the<br>
file data.<br>
