I have to domains, 1. xyz.abc.com 2. xyz.abbc.com Now when I am trying to change the domain of the cookie at the toplevel the below iRule isn't working. when HTTP_RESPONSE { set a ".abc.com" set b ".abbc.local" foreach mycookie [HTTP::cookie names] { set cookieDomain [HTTP::cookie domain $mycookie] if {$cookieDomain contains $a } { HTTP::cookie domain $mycookie $a } elseif {$cookieDomain contains $b } { HTTP::cookie domain $mycookie $b } } } There is no response of the iRule. Expected: cookie domain for xyz.abc.com should be .abc.com and for xyz.abbc.com should be .abbc.com Help?

Finally I was able to set the cookie domain to toplevel by using the following iRule. Cookies are set to toplevel domain now by using HTTP::host and comparing directly with the domain values I have. What do you think about the following iRule? Any flaws? when HTTP_REQUEST { log local0. "Cookie names in received request: [HTTP::cookie names] from IP: [IP::local_addr]" set httphost [HTTP::host] } when HTTP_RESPONSE { foreach mycookie [HTTP::cookie names] { log local0. "Host : $httphost" if { $httphost ends_with ".abc.com" } { HTTP::cookie domain $mycookie ".abc.com" } elseif { $httphost ends_with ".abbc.com" } { HTTP::cookie domain $mycookie ".abbc.com" } else { log local0. "Not a single cookie domain matched :" } } }
