F5 BIG-IP - Forward traffic to all nodes in a pool?

Does anybody know if this is possible? I'm a little unsure how this would actually work from a clients perspective, but i'm checking if this is possible. Can I forward all traffic onto all nodes within a pool? I am looking at the 'clone' function in irule, but it doesn't seem to be working as I'd hoped.

To make things more difficult I'm having to use SSL bridging on this virtual server. The irule i've got so far is:

when CLIENT_ACCEPTED {

clone pool pool1 member 10.10.10.1 8440

clone pool pool1 member 10.10.10.2 8440

clone pool pool1 member 10.10.10.3 8440

clone pool pool1 S member 10.10.10.4 8440

}

Using this code, I get "connection refused" when hitting the virtual server. If I change the second line to:

pool pool1 member 10.10.10.1 8440

It works, or at least, the client gets content back, however the stats show 10.10.10.1 as having a connection, and also 10.10.10.4 but not the other two!

Any ideas?

Thanks in advance
