Trying to do session persistence based on uri between multiple pools and need assistance with iRule, it is partially working and need some insights how to get it working.

if {([string tolower[HTTP::uri] matches_regex {\/wps\/myportal\((?!\?).)*$}] and ([string tolower [HTTP::cookie exists portal2_cookie]]))} {
pool login_debug_pool
persist cookie rewrite l_cookie 0
}

Above logic is being intercepted in F5 but all the requests not loading completely. If I delete the cookie portal2_cookie from browser tab manually, then it works properly.

I'm trying to figure out a way on how to delete the cookie in the response or if there is any way to get all the subsequent uri's loaded when switching pools with persistence.

Thanks,
