Events
======

Events allow you to capture metrics on your application’s HTTP calls. Use events to monitor:

 * The size and frequency of the HTTP calls your application makes. If you’re making too many calls, or your calls are too large, you should know about it!
 * The performance of these calls on the underlying network. If the network’s performance isn’t sufficient, you need to either improve the network or use less of it.

### EventListener

	Expires              time.Time // Is only used in POST/PUT operations

	DeleteMarker            bool // Is only set in DELETE operations for delete marker replication
	CheckDMReplicationReady bool // Is delete marker ready to be replicated - set only during HEAD
	Tagging                 bool // Is only in GET/HEAD operations to return tagging metadata along with regular metadata and body.

# The Go Programming Language

Go is an open source programming language that makes it easy to build simple,
reliable, and efficient software.

`@ExperimentalOkHttpApi`. You can safely use this release in production.

 *  Fix: Attempt to read the response even if sending the request failed. This makes it possible
    to handle response statuses like `HTTP/1.1 431 "Request Header Fields Too Large`.

 *  Fix: Handle multiple 1xx responses.

In the same way, you can use `finally` to make sure the exit steps are executed, no matter if there was an exception or not.

## Sub-dependencies with `yield` { #sub-dependencies-with-yield }

You can have sub-dependencies and "trees" of sub-dependencies of any size and shape, and any or all of them can use `yield`.

    OkHttp used _get_ and _set_ prefixes sporadically which make the API
    inconsistent and awkward to explore.

 *  **OkHttpClient now implements the new `Call.Factory` interface.** This
    interface will make your code easier to test. When you test code that makes
    HTTP requests, you can use this interface to replace the real `OkHttpClient`
    with your own mocks or fakes.
