Requirements
------------

OkHttp works on Android 5.0+ (API level 21+) and Java 8+.

OkHttp depends on [Okio][okio] for high-performance I/O and the [Kotlin standard library][kotlin]. Both are small libraries with strong backward-compatibility.

We highly recommend you keep OkHttp up-to-date. As with auto-updating web browsers, staying current
with HTTPS clients is an important defense against potential security problems. [We

 *    will be used to authenticate the client's certificate chain. Typically this is not the same
 *    set of root certificates used in server authentication. Instead it will be a small set of
 *    roots private to an organization or service.

    `OkHttpClient.setCache(...)` instead of `OkHttpClient.setResponseCache(...)`.
