BFilter 1.1

BFilter is a filtering web proxy. It was originally intended for removing banner ads only, but since then its capabilities have been greatly extended.
Unlike most of the similar tools, it doesnt rely on blacklists (although it does support them). The problem with blacklists is that advertisers are always one step ahead. You see an ad slip through, you update your blacklist, and in case it didnt help, you add a new entry yourself.
Once I got tired of that, I decided to write a proxy that would detect ads heuristically, much like modern anti-virus software manages to detect many viruses unknown to it.
Main features:
- HTTP/0.9 - HTTP/1.1, WebDAV support.
- Persistent connections (HTTP/1.1 only).
- Pipelining (HTTP/1.1 only).
- HTTP compression.
- Forwarding to another proxy (HTTP proxies only).
- A built-in javascript engine.
- Heuristic Flash analyzer.
- Ability to apply regular expressions to a page.
- Blacklists, whitelists, hint lists.
- All processing is done on the fly. It doesnt load the whole page before processing.
Enhancements:
- BFilter now caches external scripts it fetches for analyzing.
- Filtering accuracy was improved.
- Added a workaround for "Error decompressing response" problem with Opera and some websites.
- JavaScript engine was updated.
- Windows and Mac OS X build systems now use CMake.
