*  Fix: Don't crash decompressing web sockets messages. We had a bug where we assumed deflated
    bytes in would always yield deflated bytes out and this isn't always the case!

 *  Fix: Reliably update and invalidate the disk cache on windows. As originally designed our
    internal `DiskLruCache` assumes an inode-like file system, where it's fine to delete files that

   * A buffer for [upstreamReader] to use when pulling bytes from upstream. Only the

 * Supported on OpenJDK 9+ via SSLParameters and SSLSocket features.
 *
 * ### Trust Manager Extraction
 *
 * Supported on Android 2.3+ and OpenJDK 7+. There are no public APIs to recover the trust
 * manager that was used to create an [SSLSocketFactory].
 *
 * Not supported by choice on JDK9+ due to access checks.
 *
 * ### Android Cleartext Permit Detection

Use MockWebServer the same way that you use mocking frameworks like
[Mockito](https://github.com/mockito/mockito):

1. Script the mocks.
2. Run application code.
3. Verify that the expected requests were made.

Here's a complete example:

```java
public void test() throws Exception {
  // Create a MockWebServer. These are lean enough that you can create a new
  // instance for every unit test.

      "FGHIJKLMNOPQRSTUVWXYZ",
    )
    inputStream.close()
    assertContent("ABCDEFGHIJKLMNOPQRSTUVWXYZ", getResponse(newRequest("/")))
  }

  /**
   * We've had a bug where we forget the HTTP response when we see response code 401. This causes a
   * new HTTP request to be issued for every call into the URLConnection.
   */
