Hi Grant,

this seems to be a bug. I supposes xSocket interprets the http
connection as 'non persistent' by receiving the CONNECT response. This
could be the reason why the connection is disconnected. 

Please file the bug

Thanks

	First, very nice job with this library. Its very well organized
and works well. 
	Currently, using xsocket 2.1 and http 2.0 beta 1. 

	When connecting to https server through a proxy the following
combination does not work. 

	-------------------------------------------- 
	HttpRequest connect_http = new
HttpRequest("CONNECT","somecompany.com:443"); 
	... 
	NonBlockingConnection proxy_conn = new
NonBlockingConnection("proxy.net",8080,ssl_context,false); 
	HttpClientConnection http_conn = new HttpClientConnection
(proxy_conn); 

	IHttpResponse connect_response = proxy_conn.call(connect_http); 

	Thread.sleep(2000); 
	System.out.println("Activating Secure Mode ..."); 
	http_conn.activateSecureMode(); 

	Getting the following exception: 

	Activating Secure Mode ... 
	java.nio.channels.ClosedChannelException 
	        at
org.xsocket.connection.AbstractNonBlockingStream.readByteBufferByLength(
AbstractNonBlockingStream.java:546) 
	        at
org.xsocket.connection.NonBlockingConnection.readByteBufferByLength(NonB
lockingConnection.java:1259) 
	        at

kingConnection.java:1212) 
	        at
org.xsocket.connection.http.AbstractHttpConnection.activateSecuredMode(A
bstractHttpConnection.java:429) 
	-------------------------------------------- 

	However, the following works fine 

	-------------------------------------------- 
	 static String CONNECT_STRING = "CONNECT somecompany.com:443
HTTP/1.1\r\n" 
	                  +"Connection: keep-alive\r\n" 
	                  +"Proxy-Connection: keep-alive\r\n" 
	                  +"Pragma: no-cache\r\n" 
	                  +"Keep-Alive: 300\r\n" 
	                  +"Host: somecompany.com:443\r\n" 
	                  +"\r\n"; 
	NonBlockingConnection proxy_conn = new
NonBlockingConnection("proxy.net",8080,ssl_context,false); 
	proxy_conn.write(CONNECT_STRING); 
	proxy_conn.flush(); 

	while(not_finished_reading) { 
	  proxy_conn.read(...) 
	} 

	proxy_conn.activateSecuredMode(); 
	-------------------------------------------- 

	After stepping through the code a bit it seems that the channel
is being closed after the CONNECT 
	request is processed. So the subsequent handshake fails. You
need to be stepping in the dispather and main 
	threads to see this. 

	Regards, 
	Grant
