Redirect trafic http to specific pool member and ftp trafic to another pool member

The easiest way is to create two virtual servers, both with the same address, one listening on port 80 (for HTTP) and another on port 21 (for ftp). Then just assign the two virtuals their own default pool of servers. No iRules involved at all.

 

 

If you need to use a wildcard virtual (listening on all ports), then you are going to have to do a TCP::collect to get the payload content and inspect it to determine which protocol it's using. Search the forums for TCP::collect and I'm sure you'll find several examples of using it. Once you have determined which protocol you are receiving, you can use the "node" command to send that connection to the specfied backend server.

 

 

Here's some pseudo code for the node command.

 

 

...
if { traffic is determined to be HTTP } {
  node 10.10.10.10 80
} elseif { traffic is determined to be FTP } {
  node 10.10.10.20 21
}
...
