Example 1 with StatusLine

use of com.squareup.okhttp.internal.http.StatusLine in project grpc-java by grpc.

the class OkHttpClientTransport method createHttpProxySocket.

private Socket createHttpProxySocket(InetSocketAddress address, InetSocketAddress proxyAddress, String proxyUsername, String proxyPassword) throws IOException, StatusException {
