Within a Content Delivery Network there are 3 ways to get a client to the closest Content Engine for delivery of Content. One way is using Simplified Hybrid Routing. The other 2 ways are:

A.
Using WCCP on a router for transparent redirection or setting the proxy settings in a browser point to the closest Content Engine.

B.
Using WCCP on a router for transparent redirection or using DNS to resolve to the correct Content Engine.

C.
Using DNS to direct the request to a content router and using a HTTP redirect to have the client go directly to the Content Engine.

D.
Using a Coverage Zone file on the client and then using an HTTP redirect to have the client redirect to the closest Content Engine.

E.
Setting up proxy settings in a browser pointing to the closest CE or using DNS to provide the IP address of the closest CE.
