small question in "persist"

is universal persistence applicable?

I think you'd need to add a cookie persistence profile to use any of the persist cookie iRule commands. The simplest solution from a BIG-IP perspective would be to use cookie insert so BIG-IP doesn't need to track any sessions in its memory. If it really isn't an option to add a persistence profile, you could use persist uie from an iRule:

 from: https://devcentral.f5.com/wiki/iRules.Weblogic_JSessionID_Persistence.ashx
when HTTP_REQUEST {
    Log details for the request
   set log_prefix "[IP::client_addr]:[TCP::client_port]"
   log local0. "$log_prefix: Request to [HTTP::uri] with cookie: [HTTP::cookie value my_cookie]"

    Check if there is a my_cookie cookie
   if { [HTTP::cookie "my_cookie"] ne "" }{
       Persist off of the cookie value with a timeout of 1 hour (3600 seconds)
      persist uie [string tolower [HTTP::cookie "my_cookie"]] 3600

       Log that we're using the cookie value for persistence and the persistence key if it exists.
      log local0. "$log_prefix: Used persistence record from cookie. Existing key? [persist lookup uie [string tolower [HTTP::cookie "my_cookie"]]]"
   }
}
when HTTP_RESPONSE {
    Check if there is a my_cookie cookie in the response
   if { [HTTP::cookie "my_cookie"] ne "" }{
       Persist off of the cookie value with a timeout of 1 hour (3600 seconds)
      persist add uie [string tolower [HTTP::cookie "my_cookie"]] 3600

      log local0. "$log_prefix: Added persistence record from cookie: [persist lookup uie [string tolower [HTTP::cookie "my_cookie"]]]"
   }
}

hi,Aaron

 

yes,I don't have option to use persistence profile which is applied to VIP

 

what is needed for this persist uie?

 

it seems your example is add a new uie persistence?

 

correct me if I am wrong

actually this cookie-1 is added by me in irule in http response event

 

 

they want to send request to the node if it is sent to that node before with the cookie-1 in it

 

cookie-1 is customized.
