Looking for a (very) small http proxy in Python

[adfgvx]

Hello,

I am looking for a little script in Python that acts as a proxy. I only need
to write in a file all the headers of the http requests and of the answers.
That's all ! I know there are some proxies in Python (I looked at
sourceforge and parnassus), but they are too complicated for me, I have no
time to study and modify them to my needs.

Thank you by advance,

Bruno
