NimbostratusPersistence in an iRule
I have a virtual server with cookie persistence applied to the virtual
server and and iRule that has cookie persistence applied in each
condition. Since cookie persistence is applied to the virtual server
can I remove the "persist cookie" statements from the iRule. See config
below:
virtual virt-web-srv {
destination 10.10.50.33:http
ip protocol tcp
rules web-irule
persist cookie
profiles {
http {}
tcp {}
}
}
rule web-irule {
when HTTP_REQUEST {
set uri [HTTP::uri]
if {$uri contains "/prodweb"or $uri contains "/prodapp"} {
persist cookie
pool prod-web-pool
} elseif {$uri contains "/devweb" or $uri contains "/devapp"} {
persist cookie
pool dev-web-pool
} elseif {$uri contains "/testweb" or $uri contains "/testapp"} {
persist cookie
pool test-web-pool
} else {
HTTP::respond 404
}
}
}
Michael_YatesHi Rick,
Yes. If the cookie persistence is configured on the Virtual Server then you can remove the "persist cookie" statements from your iRule.
The BIG-IP will issue a cookie for each of the pools utilized by default when cookie persistence is configured on the Virtual Server.
Hope this helps.
Rick_110395Thanks. That does help, a lot!
