It's for research purposes. I googled and found several examples, however every single of out them looks a bit dif...

If I refresh the browser twice quickly, my proxy throws an exception, usually with no stack trace or indication of where the problem is. I have a hunch it has to do with a socket being closed prematurely by the browser, or being used for two different requests in my pr...
