NimbostratusHi,
We are kinda new to F5 and iRules so we don't really know how to create url based load balancing and we are not good at writing iRules. :)
What we want to do is that we have different pools and when example.com is typed into a browser it would direct the a user to the specific pool. When subdomain.example.com is called then it would direct them to another pool.
Could you please help with this?
Thanks in advance.
NacreousIf you just want to do simple pool forwarding based on URI, then you don't need to use iRules anymore. You can use LTM Traffic Profiles, ideal for simple logic especially if you don't know iRules. Can all be configured in the GUI
CumulonimbusIf you're not good at writing iRules, use LTM policy with 2 rules
NimbostratusHere's an iRule I use for this type of thing. It uses a "Datagroup" that you can update the http host header to pool mapping to do what you want.
Create a Datagroup "HOST_2_POOL_DataGroup" with entries like:
"expample.com" := "APP_Pool01",
"subdomain.example.com" := "APP_Pool02",
`
`when HTTP_REQUEST {
set pool_select_value [class lookup [string tolower [HTTP::host]] HOST_2_POOL_DataGroup]
if {[active_members $pool_select_value] > 0 } {
log local0.notice "available pool members"
pool $pool_select_value
} else {
HTTP::respond 503 content "No active pool members in pool"
}
}
