In ProxySG, which caching optimization technique opens multiple connections for simultaneous requests?

In ProxySG, pipelining is a caching optimization technique that allows the client to send multiple requests over a single connection to the server without waiting for the corresponding responses. This method significantly enhances performance by minimizing latency, as it enables the transfer of multiple pieces of data in a more efficient manner.

When multiple requests are sent in a pipeline, the proxy can dispatch them to the server concurrently. Instead of establishing new connections for each request—an operation that can introduce delays—pipelining allows existing connections to be utilized, leading to better resource use and faster content retrieval.

This technique is particularly advantageous in scenarios where the same server is handling numerous requests from clients, making it more efficient than other methods that might establish separate connections for each request or rely on sequential processing. Through pipelining, the ProxySG can enhance overall throughput and response times.
