Gets or sets the default cache policy for this request.
Assembly: System (in System.dll)
This policy is used for this request if the following conditions exist:
There is no DefaultCachePolicy property specified for this request.
The machine and application configuration files do not specify a cache policy that is applicable to the Uniform Resource Identifier (URI) used to create this request.
The cache policy determines whether the requested resource can be taken from a cache instead of sending the request to the resource host computer.
A copy of a resource is only added to the cache if the response stream for the resource is retrieved and read to the end of the stream. So another request for the same resource could use a cached copy, depending on the cache policy level for this request.
