SSL, Cookie persistence, and Redirection

In this line of code:

 

 

HTTP::cookie insert name my_cookie value [concat [virtual name] [LB::server]]

 

 

Does the virtual name get concatenated to the LB::server information, or vice versa?

 

 

Also, what is the method to check if a resource is local? For instance, if I receive from the cookie (server) 10.1.1.50 (port) 80, what command verifies that this resource exists?

 

 

Thanks. I like that methodology much better than populating an array.
