    If it is a query parameter you can do it with something like this:

    when HTTP_REQUEST {
    if {[string tolower [URI::query [HTTP::uri] "User_Info"]] equals "xx"}{
        pool "pool-1"
    }
    else {
        pool "pool-2"
    }
}

      If your POST body is XML you could use a XML profile to direct your traffic to a pool based on that value. https://support.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/ltm-implementations-11-6-0/3.html If its some other kind of body you may have to get more creative and parse the HTTP payload using HTTP::collect, https://clouddocs.f5.com/api/irules/HTTP__collect.html, and the HTTP_REQUEST_DATA event.
