Re: [xSocket-develop] Running out of connections with HttpClient?

[Gregor R. <gre...@go...>]

Hi Ian,

the constructor you used -> new PostRequest(node.getAddress()+"/", new
String[0]) is a convenience constructor to create a x-www-form-urlencoded
POST request. By setting the body (post.setBodyDataSource(bytes, null)) you
declare the encoding with null. Based on this xSocket-http creates a POST
request header like

POST / HTTP/1.1
Content-Length: 3
Content-Type: application/x-www-form-urlencoded; charset=null
HOST: localhost:30002

As you see the charset is set with null. This is a bug, which I have already
fixed in the trunk. I suppose this causes the strange behaviour you
reported.

I'm not sure if you really want to use the content-type
x-www-form-urlencoded. The PostRequest of the current trunk has been
enhanced by a constructor, which accepts the parameters url, contentType and
a byte array. E.g.
new PostRequest("http://localhost:30002/", "application/octet-stream", new
byte[] { 65, 87, 78});

Regarding to the HttpClient you don't have to close a request or response.
The HttpClient will automatically close or reuse the underlying http
connection. What you should do, is to close the HttpClient. By closing the
HttpClient the internal cached (open) connections will be closed.
