CORS proxy troubles: 404 not found because of extra params

Question

I have:

var url = 'http://cs7-5v4.vk-cdn.net/p10/da565dec1e4757.mp3?extra=30Z5mfWgb6cqPGfxDGrp1D7QgILPRF6pH1pUjnVlGdATqfZei1PFHNheoT19Hw41Oau34IsRFAe6f971LFoxoruML5MoGXqz';
$.get('http://www.corsproxy.com/' + url);

Result: 404 Not found

Problem: corsproxy add &from=54.161.20.93&hash=8e1a65aef18d9a to the end of the url. I assume that is the reason.

Question: Am I right about the reason? How to bypass it?

P.S. I can listen music by my url if I would pass it manually into as browser

Request details

Another suggestion: is that corsproxy returns the response not directly to the client but to the domain. Means my server should match that response url, and my server get 404 error.

$.ajax({
  url: 'cs7-5v4.vk-cdn.net/p10/2f9c8a5946540e.mp3?extra=BAgwPhrBv7Elf0H2dBRClDwFZhvc1adQeXmVxGmZh7HYu3SOCp1Fe8mZbkZE9yI2PvShuW0iYXhl0RPAtBWJuNPgjVA',
  success: function() { alert(success); },
  error: function(xhr) { document.body.innerHTML = xhr.responseText; }
})

inserts into bod next:

where app.js is my core url mapping node file.

Answer 1

I'm not certain about this, but I think you just need to strip out the "http://" from your url as per the documentation here: http://www.corsproxy.com/

Also the URL you gave in the example gives a 404 by itself.

Hope this helps,
