can we direct traffic based on their cookie to a particular server using iRules

Hi,

 

can we direct traffic based on their cookie to a particular server using iRules?

 

The requirement is as below. If mylogin.sgx.com and mylogin.access.sgx URLs contain this cookie- amlbcookie=01, then route all requests to the PDC OpenAM server.

 

If mylogin.sgx.com and mylogin.access.sgx URLs contain this cookie- amlbcookie=03, then route all requests to the SDC OpenAM server.

 

Thanks in advance for your help.

    You can use an iRule with the next condition in order to check if the cookie "amlbcookie" exists

     

    if { [HTTP::cookie exists "amlbcookie"] }

    I aint good at Irule 🙂 But logic would be like this I believe,

    when HTTP_REQUEST {
        set DEBUG 0
        set PDC_OpenAM_pool ""PDC_OpenAM_pool""
        set SDC_OpenAM_pool ""SDC_OpenAM_pool""
        if { [HTTP::cookie exists ""amlbcookie""] } 
            {
            if { [HTTP::cookie value ""amlbcookie""] equals ""01"" } 
                {
                if { $DEBUG } { log local0. ""CLIENT IP is [IP::client_addr] $PDC_OpenAM_pool selected"" }
                pool $PDC_OpenAM_pool
                } 
            elseif {[HTTP::cookie value ""amlbcookie""] equals ""03"" } 
                {
                if { $DEBUG } { log local0. ""CLIENT IP is [IP::client_addr] $SDC_OpenAM_pool selected"" }
                pool $SDC_OpenAM_pool
                }
            }
                  }

    You can also use active_members logic to control redundancy.
