**This release introduces new Kotlin-friendly APIs.** When we migrated OkHttp from Java to Kotlin in
OkHttp 4.0, we kept our Java-first APIs. With 5.0 we're continuing to support Java and adding
additional improvements for Kotlin users. In this alpha we're excited to skip-the-builder for
requests and remove a common source of non-null assertions (`!!`) on the response body.

      // Parse each header.
      for (i in 0 until responseHeaders.size) {
        if (!responseHeaders.name(i).equals(HEADER_WEB_SOCKET_EXTENSION, ignoreCase = true)) {
          continue // Not a header we're interested in.
        }
        val header = responseHeaders.value(i)

        // Parse each extension.
        var pos = 0
        while (pos < header.length) {

          result.add(trustedCert)
        }
        if (verifySignature(trustedCert, trustedCert, result.size - 2)) {
          return result // The self-signed cert is a root CA. We're done.
        }
        foundTrustedCertificate = true
        continue
      }

      // Search for the certificate in the chain that signed this certificate. This is typically

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.RequestBody;
import okhttp3.Response;

public final class PostMultipart {
  /**

    try {
      while (currentTask != self) {
        taskRunner.condition.await()
      }
    } finally {
      serialTaskQueue.remove(yieldCompleteTask)
    }

    // If we're yielding until we're exhausted and a task run, keep going until a task doesn't run.
    if (strategy == ResumePriority.AfterOtherTasks && otherTasksStarted) {
      return yieldUntil(strategy, condition)
    }
  }

 *     }
 *   }
 *
 *   public void onFailure(Call call, IOException e) {
 *   ... // Handle the failure.
 *   }
 * });
 * ```
 *
 * These examples will not work if you're consuming the response body on another thread. In such
 * cases the consuming thread must call [close] when it has finished reading the response
 * body.
 *
 * ### The response body can be consumed only once.
 *

The response answers the request with a code (like 200 for success or 404 for not found), headers, and its own optional body.

## Rewriting Requests

When you provide OkHttp with an HTTP request, you’re describing the request at a high-level: _“fetch me this URL with these headers.”_ For correctness and efficiency, OkHttp rewrites your request before transmitting it.

          exchange.noRequestBody()
          if (!exchange.connection.isMultiplexed) {
            // If the "Expect: 100-continue" expectation wasn't met, prevent the HTTP/1 connection
            // from being reused. Otherwise we're still obligated to transmit the request body to
            // leave the connection in a consistent state.
            exchange.noNewExchangesOnConnection()
          }
        }
      } else {
