+### Per-message Compression ###
+
+**websocket-sharp** supports **[Per-message Compression]**.
+
+If you want to enable this extension as a WebSocket client, you should do like the following.
+
+```cs
+ws.Compression = CompressionMethod.DEFLATE;
+```
+
+And then your client sends the following header in the opening handshake to a WebSocket server.
+
+```
+Sec-WebSocket-Extensions: permessage-compress; method=deflate
+```
+
+If the server supports this extension, responds the same header. And when your client receives the header, enables this extension.
