Target redirect URL - https://test.test.com/linkredirectservice/drl?desktop=Invoice&docid=%7BC2827ADC-C4B5-4B62-9024-C7848E7CAF5F%7D

 

Note - Target URL redirect has docid value which need sto be taken from the source URL and also the { and } in the source URL docid value needs to be conver their ascii values accordingly.

    I'm just learning iRules myself but will try to help.  There should be a pre-installed redirect Irule on the LTM.  I found one named "_sys_https_redirect".  Looks like this.

    when HTTP_REQUEST {
    HTTP::redirect https://[getfield [HTTP::host] ":" 1][HTTP::uri]
    }

    Below is one of my companies redirects.

    when HTTP_REQUEST {
    if { [string tolower [HTTP::host]] equals "????.com" } {
    HTTP::respond 301 Location "https://???.com[HTTP::uri]"
    }
    }

     

    Hope this helps.
