ofLoadURL() function does not close the created socket

[jmiguelff]

So this problem can be spoted if you use the ofLoadURL() function on the update(). After a while you will have a bunch of sockets with the WAIT_CLOSE status and the application will fail. On win10 if you run netstat -an on the command line you will see a bunch of sockets being used there.

After some research I found out the problem may be on this function: ofHttpResponse ofURLFileLoaderImpl::handleRequest(ofHttpRequest request).

This function creates a new instance of HTTPClientSession every time it runs, HTTPClientSession * httpSession = new HTTPClientSession(uri.getHost(), uri.getPort());. And after receiving the info from the link you provided it does not destroy this instance leaving the socket open.

As I reported on the forum, https://forum.openframeworks.cc/t/repeat-usage-of-ofloadurl-causes-i-o-error-no-buffer-space-available/23747/1 I found out a quick fix (explained there). However, I think it should be better to just use the deconstructor after getting the information from the web link.

I hope this information is enough for you guys to understand the issue 💃
