I don't know how to do this.  But I think I might know why it doesn't work.

Your browser thinks it is going to site www.abcd.com and sends a request li=
ke
this:
    GET /index.html
your ipchains redirects this to FilterProxy, which sees the non-absolute URL
/index.html.  FilterProxy can't figure out what site you were trying to get
because there isn't enough information in the request.

Can you turn on "dump headers to log file" on the Header config page, and
enable debug on the main page, and send me some of your logs?
