OkHttp URLConnection
====================

This module integrates OkHttp with `Authenticator` and `CookieHandler` from `java.net`.

This module is obsolete; prefer `okhttp-java-net-cookiejar`.

Interceptors
============

Interceptors are a powerful mechanism that can monitor, rewrite, and retry calls. Here's a simple interceptor that logs the outgoing request and the incoming response.

```java
class LoggingInterceptor implements Interceptor {
  @Override public Response intercept(Interceptor.Chain chain) throws IOException {
    Request request = chain.request();

    long t1 = System.nanoTime();
