iRule to load balance traffic based on directory

Hi all,

 

I am new to iRules and deploying a F5 solution which required traffic to be load balanced based on the directory structure. To give you an overview here's what the setup looks like this:

 

• Single F5 VIP pointing to multiple pools (4 pools)
• The pools are based on the directories they host
• Pool members are same, however the service port is different

Here's my iRule

 

when HTTP_REQUEST { switch -glob [string tolower [HTTP::path]] { "/dir1"{ pool pool-1 } "/dir2"{ pool pool-1 } "/dir3"{ pool pool-1 } "/dir4"{ pool pool-2 } "/dir5"{ pool pool-2 } "/dir6"{ pool pool-3 } "/dir-a/dir-b*"{ pool pool-3 } } }

 

I'd like to know if the above rule is valid and if there's a better way of doing this. Any help will be appreciated.
