CDN Request Pipelining

Not all Content Delivery Networks (CDN) request pipeline (also known as Pre Caching System).

Request pipelining is a technique to reduce the number of origin hits for simultaneous requests. If there are three simultaneous requests for a non cached item then one server will make the request to the origin and the other two servers will wait until the server making its request has completed and then return the cached content.

The impact of having no request pipelining depends on the nature of what your origin is serving. If origin hits are particularly heavy CPU/IO wise and/or you have flash traffic (large amount in very short window) then you will definitely want your CDN to request pipeline.
