 * This is because those two hosts share the same IP address. This is an old, bad design decision

 * because unequal URLs may be equal because of how they are hosted.

 *  Fix: Calling `disconnect()` on a connecting `HttpUrlConnection` could cause it to retry in an
    infinite loop! This regression was introduced in OkHttp 2.7.0.
 *  Fix: Drop cookies that contain ASCII NULL and other bad characters. Previously such cookies
    would cause OkHttp to crash when they were included in a request.
