I application will use proxys, some of them, how to find out the download speed provided by each proxy server, I want to use the proxy server with the highest speed first, looking for an easy implementation.
Please submit suggestions, rude ideas are also welcome.
Thanks in advance.
You can use multiple background workers created dynamically to start downloads from each proxy server.
Using an algorithm based on http://www.devtoolshed.com/content/c-download-file-progress-bar
