iRules: Pool selection by URI and cookies

Hi Kai,

there are at least two aspects to consider:

1) a URI will start with a slash

/

character. So the validation has to match a string of i.e "/foo", "/foo*", "*foo"

Without a literal slash or a wildcard as

*

in case you are using globbing you will not get a match.

2) The function

HTTP::cookie names

returns a list. A list cannot be matched versus a jump table as used by the

switch

command.

You want to use exact matches for an exact cookie name by using i.e.:

foreach cookie_name [HTTP::cookie names] {
   switch $cookie_name {
       "foo_named_cookie" { 
           
           return
       }
       "bar_named_cookie" { 
           
           return
       }
   }
}

It will be important to use a

return

after running the action for a match to exit the evaluation.

Thanks, Stephan
