Are there any free, light-weight, single-process (e.g. multi-threaded, asyncore) HTTP forward proxy software?
Tinyproxy works great, but it uses multiple processes like (Apache's) prefork. HAProxy and nginx are reverse proxies don't seem to have forward proxy functions. Squid is huge...
Privoxy is a "non-caching web proxy with advanced filtering capabilities". But... What is wrong with using multiple processes? Due to the nature of how processes/threads are created on Linux (and some unixes) there's not much difference between a software that uses many children processes or threads...
If your concern is resource usage, you can tune tinyproxy much like apache (Min servers, min spare servers, max servers, etc...).
