Cookies shared between subdomains..pointing to same VS

HI,

 

 

Here is what I have...

 

 

A.domain1.domain.com --->>>>> points to VS say 1.1.1.1

 

B.A.domain1.domain.com --->>>>> also points to the above VS 1.1.1.1

 

 

http persistance is cookie.

 

 

When a user login to the system using A.domain1.domain.com the F5 sets a cookies for this user and it uses this cookie to stick the user to a particular server say server 1; and that works fine.

 

 

Lets say now the user accesses the B.A.domain1.domain.com site and it is required that are also kept to the same server as the A.domain1.domain.com (server1 from above).

 

 

 

Any thoughts ? thanks

    You can set the domain on the persistence cookie using a rule:

    This rule assumes you're using the default persistence cookie name (BIGipServerPOOLNAME). If you've customized the cookie name in the persistence profile you could hardcode it in the rule and remove the LB_SELECTED event.

 when LB_SELECTED { 
     get the pool name used for this request 
    set my_pool [LB::server pool] 
 } 
 when HTTP_RESPONSE { 
  
     Check if the persistence cookie exists in the response 
    if {[HTTP::cookie count] > 0 and HTTP::cookie exists "BIGipServer$my_pool"} { 
  
        set the domain attribute on the persistence cookie to .example.com. 
       HTTP::cookie domain "BIGipServer$my_pool" ".example.com" 
     
 }
