irule feature question
Site has multiple VS, A, B, C, D...user 1 comes in and gets directed to VS A. VS A has coookie insert persistence. User gets a cookie. Something on the user side (AOL proxy) changes and user then g...
we needed logic to validate that the destination pool is actually up so the irule now looks like below...problem is that if that original pool is down and the user gets directed to the default pool of the VS they now have 2 cookies. If the original pool comes back up, they'll get sent to it and lose whatever shopping they've done on the default pool. Is there any way to remove the cookie from the original pool if it's down ?
when HTTP_REQUEST {
set CookiePool [findstr [HTTP::cookie names] "BIGipServer" 11 " "]
if { $CookiePool !=""} {
if {[active_members $CookiePool] > 0} {
pool $CookiePool
log local0. "sending [IP::client_addr] coming in on [IP::local_addr] to pool $CookiePool" }
else {
pool [LB::server pool]
log local0. "sending [IP::client_addr] coming in on [IP::local_addr] to pool [LB::server pool] because original pool $CookiePool is down"
}
}
}
