Massive session creation in Threads about thredds HOT 2 CLOSED

I implemented a solution to our problem which allows to do the process using only one session. The approach makes use of a new HttpSession class (HttpCloseableSession) which has CookieStore, HttpContext, CredentialsProvider and CloseableHttpClient.
This CloseableHttpClient is built by using the builder which allows you to set the proxy and the configs you’ve done in the HTTPSession setting area. I also created a new HTTPCloseableMethod class which has a similar approach to the original one but using the new features.

Finally, I added two new methods to HTTPFactory to use a custom GET and HEAD. The new methods only need the URL because the HTTPCloseableSession is static. The new HTTPCloseableMethod accepts a HTTPSession.Methods and contains the execute method. When the opendap calls to this get, it is able to call execute and close the client (you can take a look to DConnect2.java

How can we make a request now?

It is very simple:

HTTPCloseableSession.setCredentials("username", "password");
HTTPCloseableMethod method = HTTPFactory.GET(urlString);
int statusCode = method.execute();
is = method.getResponseAsStream();
method.close();

You can see my approach is ready to basic authentication but can be used with others. I've tried not to modify so much of your code, only the esential part to make it work but I think it can be a good way to start.

Please take a look

The deprecations are because we were forced to switch to Apache httpclient 4.4.x
before we were ready. The existing code is based on Apache httpclient 4.3.x.
The 4.4 code is substantially refactored compared to 4.3. The 4.3 API is supported,
but deprecated, so that is why you are seeing them.
The complete conversion of the code to 4.4 is underway, but probably will not
be available until version 5 of thredds.
BTW, you say "my approach is ready to basic authentication but can be used with others."
Can you give specifics, say for URS. We already or plan to support a wide variety of authorization mechanisms: Basic, ESG (client-side certificates), URS (redirection) and soon to be others.
