iRule for URL persistence

Thank you very much Chris~~

 

 

Actually the 6 characters string is a random number that is generated from the web client. (Once the random number is generated, that number will be the same during the transactions) So i need to use that string as the identifier to persist the connection.

 

 

 

 

http://test.big-ip.com/install/123456/whateverxxxxxx

 

 

 

 

In my case, the 5th field of the url is the 6 characters string. (is that right?)

 

 

So to get the 5th field in the url, i used [getfield [HTTP::uri] "/" 5] .

 

 

 

 

when HTTP_REQUEST {

 

set session_id [getfield [HTTP::uri] "/" 5]

 

if {$session_id ne ""} {

 

persist uie $session_id 1800

 

}

 

}

 

 

 

I tried the above iRule in my F5 but it seems not work, the connection cannot be persist.

 

 

any thing wrong in my iRule ?

 

 

Thank you for your help.
