Squid (http://www.squid-cache.org/) will filter based on HTTP methods, as
well as lots of other things. Remember, though, that filtering on HTTP
methods like POST or HEAD is nearly useless if you don't deny the CONNECT

Subject: [fw-wiz] Filtering proxy for HTTP POST requests

Does anyone have suggestions/recommendations for a HTTP proxy (cheap/free)
which can filter based on content. Preferably something capable of Bayesian
analysis of content? It needs to work in ISP environments, so transparent
proxy support would be ideal.

Traffic to be filtered is outbound from the browser to the server.
