proxy tiny free proxy server

3Proxy tiny free proxy server previously known as 3[APA3A] tiny freeware proxy (pronounce it as "Zaraza tiny freeware proxy") is really tiny cross-platform (Win32/Win64&Unix) proxy servers set. It includes HTTP proxy with HTTPS and FTP support, SOCKSv4/SOCKSv4.5/SOCKSv5 proxy, POP3 proxy, FTP proxy, caching DNS proxy, TCP and UDP portmappers. You can use every proxy as a standalone program (socks, proxy, tcppm, udppm, pop3p) or use combined program (3proxy). Combined proxy additionally supports features like access control, bandwidth limiting, limiting daily/weekly/monthly traffic amount, proxy chaining, log rotation, syslog and ODBC logging, etc. It's created to be small, simple (I'd like to say secure - but it's just a beta) and yet very functional. It may be compiled with Visual C or gcc. Native Win32 version included in archive and supports installation as NT/2K/XP service. Currently 3proxy is tested to work under Windows 98/NT/2000/2003/XP/x64, FreeBSD/i386, NetBSD/i386, OpenBSD/i386, Linux/i386, Linux/PPC, Linux/Alpha, Mac OS X/PPC, Solaris 10/i386. See Release Notes and Changes for features list.
