    Hello Muhannad.

     

    Tried this code and it works like a charm.

    when HTTP_REQUEST {
    	set fqdn_name [HTTP::host]
    }
    when HTTP_RESPONSE {
    	set location [HTTP::header Location]
    	set port [URI::port $location]
    	set n_path [URI::path $location]
    	set n_basename [URI::basename $location]
    	set n_query [URI::query $location]
    	if { [HTTP::is_redirect] }{
    		if { $port eq 80 }{
    			HTTP::header replace Location "https://$fqdn_name$n_path$n_basename?$n_query"
    		}
    	}
    }

    Without iRule, this is the server response.

    < HTTP/1.0 302 Found
    < Location: http://example.local:80/xx/ApplicationsLogin?applicationId=MTA=&applicationInstanceId=MQ==
    < Server: BigIP
    < Connection: Keep-Alive
    < Content-Length: 0

    And this is the response with the iRule.

    < HTTP/1.0 302 Found
    < Location: https://example.local/xx/ApplicationsLogin?applicationId=MTA=&applicationInstanceId=MQ==
    < Server: BigIP
    < Connection: Keep-Alive
    < Content-Length: 0

    Regards,

    Dario.
