Sorry, I posted the previous comment then saw your follow-up. Unfortunately, the URI you provide isn't really legal, and the 

HTTP::
handling primitives are sensitive to this fact. If you cannot alter this client behavior, then it looks like you will have to bypass the HTTP events and primitives and directly read the data. 

when CLIENT_ACCEPTED {
    TCP::collect
}

when CLIENT_DATA {
    set guid [findstr [TCP::payload] "docid=" 6 &]
    TCP::release
}

when HTTP_REQUEST {
    if { [info exists guid] && $guid ne "" } {
        HTTP::redirect "http://host.example.com/en/server/$guid"
    }
}

This assumes the entire request URI can be found in the first TCP segment. If you want it to be more robust, you'll have to expand on the logic a bit.
