Redirect Rewrite Issue

You can effectively do the same thing as the redirect rewrite option with something like the following:

when HTTP_RESPONSE {
    if { [HTTP::header exists Location] } {
         in a redirect - remap specific URLs
        HTTP::header replace Location [string map {"http://www.example.com" "https://www.example.com"} [HTTP::header Location]]
    }
}

This will allow you to control specific redirects.
