Apply Persistence Cookie on iRule (multi pool)

Hello,

We use the bellow iRule to LB to multiple pools depending on URI:

when HTTP_REQUEST {

set uri [string tolower [HTTP::uri]]

if { $uri starts_with "/content" } {
pool Pool_CRM81_Content_80

} elseif { $uri starts_with "/ecommunications_ccfra" } {
pool Pool_CRM81_ccfra

}
else {
drop
}

}

We'd Like to apply persistence cookie for Pool_CRM81_ccfra Only.

Trying to add command "persist cookie" failed,

can you give advices please?

Thank you in advance

    Hello, you may try inverse logic, if possible. So, you keep default persistence to cookie on virtual server and disable it on the pool that not persistence needed. I prefer it because I often customize cookie persistence profiles.

    when HTTP_REQUEST {
    set uri [string tolower [HTTP::uri]]
    if { $uri starts_with "/content" } {
        pool Pool_CRM81_Content_80
    } elseif { $uri starts_with "/ecommunications_ccfra" } {
        pool Pool_CRM81_ccfra
        persist none
    }
    else {
        drop
    }
}

    Just an idea!

    Regards
