cookie insert

So if I use the default F5 cookie, it names it like:

 

 

BIGipServerMYPOOLNAME

 

 

That's cool, but as a requirement from our infosec department, they want me to rename the cookie and encrypt it. Which is fine, but we have a lot of web sites. So I am wondering if i need to create one cookie profile per web site, or if there is a way to add a prefix to the end of the cookie like the default one.

 

 

for example, could i create a new cookie, name it

 

 

blah and have the f5 add the pool name to the end? Or do I just need to create one cookie profile per site?
