Abstract: Some embodiments provide a method of performing load balancing on client traffic sent to a cluster of servers that are associated with a common network address (e.g., for a VIP address associated with a service provided by the cluster of servers). The method assigns a cluster of two or more transparent load balancers to the common network address associated with the server cluster. The method configures at least two of these transparent load balancers as active transparent load balancers that concurrently (1) receive data message flows sent by clients directed to the common network address, (2) select one of the servers for each flow, and (3) forward each flow to the server selected for the flow without modifying a source network address (e.g., IP network address) of the flow.

Abstract: Described herein are systems, methods, and software to dynamically set a keepalive status for a client-server connection. In one implementation, a load balancer, providing load balancing operations for a plurality of servers, identifies a first FIN packet from a client to a server of the plurality of servers and sets a Transmission Control Protocol (TCP) keepalive status in association the connection between the client and the load balancer. The proxy further identifies a second FIN packet from the server to the client and removes the TCP keepalive status in association with the connection in response to the second FIN packet.

Abstract: The present disclosure is directed toward systems and methods for providing third-party content to users of a social networking system. For example, the disclosed systems and methods receive content associated with an offer from a third party for presentation to a user, display the content associated with the offer in a graphical user interface including a feed of social networking content associated with the user, and detecting an interaction of the user with the displayed content associated with the offer. In response to the interaction of the user, the systems and methods navigate to a website associated with the third party and display a graphical element associated with the offer overlaying a portion of the website.
