I am Marcus Kool, author of ufdbguardd, a URL filter for Squid and author of a recent patch for Squid for Regular Expression Optimisation. I am also writing a new URL filter based on ICAP and use Squid for testing.
I like to be part of squid-dev. The main reasons for wanting to join squid-dev is to monitor issues with url_rewriter and ICAP and to talk directly to the developers of Squid for questions regarding the ICAP module. I do not intend to write much code for the Squid project. Thanks Marcus
