[Boost-users] HTTP Parser

All, I am looking into developing an HTTP Proxy with content filtering and other mechanism as a fun project. Is there anything available in BOOST or in other libraries that I can read upon and use them. Specifically, I need to have HTML Parser and some sort of Proxy implementation. Few features that I aiming for are: 1. Intercept request on port 80. 2. Retrieve entire page and parse the page and check with current rules. 3. URL checking with current policy. Thanks, -AP
