    Sorry forgot the sample datagroup;

    ltm data-group internal dg_path_list { 
records { 
    "/forms" { 
         data "pool pl_foo.com_8888" 
     } 
    "/reports" { 
        data "pool pl_foo.com_9002" 
    } 
    "/SSB" { 
        data "rewrite /test" 
    } 
} 
type string 
}

Start with something like this:

when HTTP_REQUEST {
    switch -glob -- [string tolower [HTTP::uri]] {
        "/forms/*" {
            pool pool_8888
        }
        "/reports*" {
            pool pool_9002
        }
        "/ssb/*" {
            pool pool_9010
            HTTP::uri [string map -nocase {"/ssb/" "/test/"} [HTTP::uri]]
        }
        "/banneroh*" {
            pool pool_9003
        }
    }
}

where each of the pools above (ex. pool_9003) would contain and load balance both servers (BE1 and BE2). The [string map ] function for the "/ssb/*" URI simply replaces /ssb/ in the URI with /test/. This is a transparent rewrite, so the client won't see it.
