Javadoc

Invokes the request immediately, and blocks until the response can be processed or is in error.

The caller may read the response body with the response's Response#body method. To facilitate connection recycling, callers should always ResponseBody#close().

Note that transport-layer success (receiving a HTTP response code, headers and body) does not necessarily indicate application-layer success: response may still indicate an unhappy HTTP response code like 404 or 500.

isExecuted
Returns true if this call has been either #execute() or #enqueue(Callback). It is an error to execut
timeout
Returns a timeout that spans the entire call: resolving DNS, connecting, writing the request body, s
