    Indeed, %u is what I needed. Thanks.
     
    What page did you find that in the reference guide? I can't find it.

    Didn't know you could to this, but you can:
     
    Fallback hosts accept the following (taken from tech.f5.com - a great site)
     

    Format String

    Description

    %h

    host name, as obtained from the Host: header of the client

    %p

    Port, from the virtual server listening port

    %u

    URI path, as obtained from a GET/POST request

    BM_1190524
     
    BM_1191844
    Format strings for HTTP redirection
            

    An example of a fallback host string is https://%h/sample.html. In this
    string, specifying https as the protocol identifier causes the traffic to be
    redirected to that protocol instead of the standard http protocol. Also, the
    string sample.html causes the traffic to be redirected to that URI instead
    of to the standard URI specified in the HTTP header, which would normally be
    represented in the fallback string as %u.

    Table
    <http://tech.f5.com/home/bigip/manuals/bigip4_2/bigip4_2ref/BIGip_servernet.
    html#1192188> 4.8 shows some sample redirection specifications, their
    explanations, and their resulting redirection.

    Redirection string

    Explanation

    Resulting redirection

    %h:%p/%u

    No redirection (preserve host name, port, and path)

    http://www/example.com:8080/sample

    %h/unavailable

    change path, remove port

    http://www/example.com/unavailable

    https://%h/unavailable

    Specify https as protocol, remove port, change path

    https://www/example.com/unavailable

    www.sample.com:8080/%u

    Change host name and port, preserve path

    http://www.sample.com:8080/sample

    https://1.2.3.4:443/%u/unavilable.html

    Specify https as protocol, change host name, port, and path

    https://1.2.3.4:443/sample/unavailable.html

    ftp://1.2.3.4:%p/unavailable/%u

    Specify ftp as protocol, change host name and path

    ftp://1.2.3.4:8080/unavailable/sample

    rtsp://%h:554/streamingmedia/%u

    Specify rtsp as protocol, change port and path

    rtsp://www.example.com:554/streamingmedia/sample

            
    Glad you found this - I could use it myself.
     
    Regards,
    Matt

    I've searched the docs for the codes for a fallback host in a pool.
     
    I've created a fallback host, and found (just by trial and error) that
    https://foo.bar.com/%p <https://foo.bar.com/%p>
    returns https://foo.bar.com/80 <https://foo.bar.com/80>
     
    Does anyone know the other % codes?
     
    I'm trying to get the F5 do to this:
    http://www.cisco.com/warp/public/117/local_director/http_red_diffserv.html
    <http://www.cisco.com/warp/public/117/local_director/http_red_diffserv.html>

     
    Be pretty odd if a Cisco could do something a BIGIP could not.
