CachingHttpClient
in package
implements HttpClientInterface Uses HttpClientTrait

Adds caching on top of an HTTP client.

The implementation buffers responses in memory and doesn't stream directly from the network. You can disable/enable this layer by setting option "no_cache" under "extra" to true/false. By default, caching is enabled unless the "buffer" option is set to false.
