ziproxy

“Ziproxy is a forwarding (non-caching) compressing HTTP proxy server. Basically, it squeezes images by converting them to lower quality JPEGs or JPEG 2000 and compresses (gzip) HTML and other text-like data. It also provides other features such as: HTML/JS/CSS optimization, preemptive hostname resolution, transparent proxying, IP ToS marking (QoS), Ad-Blocker, detailed logging and more.

Ziproxy does not require a client software and provides acceleration for any web browser, any operational system.

Ziproxy is available as a free (FOSS) software under the GNU GPL (version 2 or higher) license.”
