NimbostratusHi,
Anyone got experience with translating Cisco ACE layer4 payload UUID pattern to F5 irules? I got this piece of Cisco config to convert to F5
sticky layer4-payload Mylayer4-payload
timeout 15
replicate sticky
serverfarm MyPool
layer4-payload begin-pattern "[/]UUID[=]" end-pattern "\x20HTTP[/]"
any advice of where do I start with this?
CirrusYou will have to use universal persistence and write an irule that will parse the payload for identifier you are looking for. Looks like your payloads contain UUID= somewhere and your ACE uses it value to persist. Do you know where that is in the payload? Is it always in the first x amount of bytes?
CumulonimbusYou can try this irule:
when HTTP_REQUEST {
extract UUID parameter value from URI
set uuid [URI::query [HTTP::uri] UUID]
if { !($uuid equals "") } {
persist uie $uuid
}
}
when LB_SELECTED {
add a persistence record when pool member is selected.
if { !($uuid equals "") } {
persist add uie $uuid
}
}
