Apache Proxy and Abstraction

[dpimental]

I am working on a project where the client is talking about apache proxy and apache proxy abstraction. This web server is hosting a real estate web site?

Can anyone shed some light on these two terms.

A proxy is a server that will accept an HTTP request and forward it to the actual server as if it had originated from itself. When the request comes back from the actual, the proxy then gives the results back to the requestor. It's usually used for either providing filtered web content to a group of clients.

I'm not familiar with the phrase "proxy abstraction" in this context.

what about the term Abstraction Layer?

That's an incredibly generic term. An abstraction layer is a layer of interface that abstracts a more specific or more complicated interface below it from whatever uses it.

An example is a database abstraction layer that provides a standard interface to many different databases hiding the specifics of each database from and providing a uniform API to the application using it.

Apache provides a protocol abstraction layer to ease the development of modules to provide protocol implemenations without having write a special interface for eash. This, however, is usually only of interest to developers.
