Persist iRule based on URI

Thanks for all your replys

I did some more testing today and have come up with some interesting finds

rather then specify a member in a pool I created 4 new pools each with one member and then rewrote the iRule to look like this

when HTTP_REQUEST {
if { [URI::decode [string tolower [HTTP::uri]]] contains "gb=" } {
persist none
log "Persist Turn Off"
}
if { [URI::decode [string tolower [HTTP::uri]]] contains "gb=4" } {
 pool member_www_04 member 4.4.4.4 80
pool member_www_04
persist source_addr 1800
log "Persist Setup to Member 4"
}
if { [URI::decode [string tolower [HTTP::uri]]] contains "gb=3" } {
 pool member_www_03 member 3.3.3.3 80
pool member_www_03
persist source_addr 1800
log "Persist Setup to Member 3"
}
if { [URI::decode [string tolower [HTTP::uri]]] contains "gb=2" } {
 pool member_www_02 member 2.2.2.2 80
pool member_www_02
persist source_addr 1800
log "Persist Setup to Member 2"
}
if { [URI::decode [string tolower [HTTP::uri]]] contains "gb=1" } {
 pool member_www_01 member 1.1.1.1 80
pool member_www_01
persist source_addr 1800
log "Persist Setup to Member 1"
}
}

This worked first time, using the Statistics page to view persistence records I saw them update and I then had my persistence to my specific webserver.

As soon as I change the line to specify a member in the pool (even thought there is only one) it stopped working.

Nothing in the logs,

Do you think this could be a bug?

TIA
