I wanted to send all the requests for same content to the same backend server. How I can do this. Are there any open source versions like HaProxy which can do this.
For example. Client 1 has requested for Content A, and my load balancer directs that request to one of the backend server say X on round robin basis. Now if I receive a request from different client 2 for the same content A, this request should be directed to the same backend server X. Are there any open source solution which can do this.
Any help/pointers would be appreciated.
