NimbostratusUDP iRule help
Can I write an iRule to distribute a UDP packet based on a specific set of bytes, say byte 10 to byte 20 is less than 100 use pool A, and if the same of set of bytes is between 100 to 200 use pool B a...

NimbostratusGreat! Thanks.
So combining that with load balancing, I would do something like:
when CLIENT_DATA {
if { [UDP::payload 50] contains "XYZ" } {
pool xyz_servers
persist uie "[IP::client_addr]:[UDP::client_port]" 300
} else {
pool web_servers
}
}
This should pick one from xyz_servers the first time if the packet contains XYZ and then persist with that server for 300 seconds, is that correct? And within the 300 seconds, if the server that was picked had crashed, the subsequent request would go to another server like how the default load balancing works, right?
