Hi Alexis, would you be able to describe your environment a little bit more? From what it sounds like, you are fronting a pool of existing node servers with LineRate. Do you have any packet captures available to help detail the conversation that is going on between the client and LineRate in addition to LineRate and the servers? Any information you can provide will be helpful to track down what might be awry here. Also, do you have the configuration of the VIP / VS / RS on LineRate handy?

 

In regard to LineRate supporting Express and WebSocket, since they use the HTTP and TCP protocols, respectively, and that is what you can load balance on LineRate, yes this should work.
