You can try to set the dst port via http-request set-dst-port

Here a untested example, just that you get the idea

backend webs2

  http-request set-var(txn.dst-port) %[url,'regsub("\/","",i)']
  http-request set-dst-port %[var(txn.dst-port)]
  
  server webserver1 0.0.0.0:0

Here is the documentation for http-request set-dst
