I have a service with one realserver which responds with a HTTP/1.1 304 Not permitted package, which is not received by the client. This if the service on the is configured as Service Type HTTP/HTTPS on the Kemp LB. If the Service Type on the Kemp is configured as STARTTLS protocols, the HTTP/1.1 304 Not permitted packet is forwardes by the LB, the client receives the packet and everthing works as expected. Due I need the content switching feature I have to use the HTTP/HTTPS service type. Therefore a fix for the issue described above is highly appreciated.
