Simplify irule (rather than if ,elseif, elseif ...)

I would recommend converting the URL to lowercase before doing the comparison. Just make sure you always enter the values you want to check for in lowercase.

So, instead of:

if {[HTTP::uri] starts_with "/atm/"

[class match [HTTP::uri] contains my_uri_datagroup] }

You would use:

if {[string tolower[HTTP::uri]] starts_with "/atm/"

[class match [string tolower [HTTP::uri]] contains my_uri_datagroup] }
