Irule to use different persistence cookie by node

I need to create an irule that use different pools according the URL requested and insert a different persistence cookie to each pool member I will try to explain the scenario. The elements are: ...
application delivery
iRules

Now I need to insert the cookie to each node. Please could you help finish this configurtion?

doesn't default cookie persistence work since pool name is included in cookie name?

by the way, i think the switch should look like this.

switch -glob [HTTP::host][HTTP::uri] {
    "URL/XXXX*" {
        pool Pool1
    }
    ...

Hi nitass,

Thanks for your answer and sorry for my delay.

I want review you suggestion and trying to configure the irule as follow 

switch -glob [HTTP::host][HTTP::uri] {
    "https://xxx.xxx.com/xxxxx" {
        pool Pool1
    }
    "https://xxx.xxx.com/yyyyy" {
        pool Pool2
    }
    "https://xxx.xxx.com/zzzzz" {
        pool Pool3
    }
}

Now the original request has changed and I need insert http cookie for each pool.

This is an example:

switch -glob [HTTP::host][HTTP::uri] {
    "https://xxx.xxx.com/xxxxx" {
        pool Pool1
        persist cookie insert <>
    }
    "https://xxx.xxx.com/yyyyy" {
        pool Pool2
        persist cookie insert <>
    }
    "https://xxx.xxx.com/zzzzz" {
        pool Pool3
        persist cookie insert <>
    }
}

Do you think that is this the correct configuration?

Many Thanks,

Jordi
