iRule Switch/If/Else | using cookie name

So you want to do a for loop on the list of cookies that the names gives you:

set cookies [HTTP::cookie names]
 loop through each cookie by name in request
foreach aCookie $cookies {
   do Stuff (tm) to $aCookie
   switch $aCookie... or whatever you want to do
}

You can do the string tolower on a cookie name, but note that in your example it would never match because it would have to be all lower "jsesssionid"

Hope this points you in the right direction!
