ASP.NET MVC removes double slashes with query parameters

Question

In my ASP.NET MVC 4 application, I have an action on the controller that receives the URL string as a parameter:

public ActionResult Get(string url)
{
    var hash = TextUtil.GenerateShortStringHash(url);
    ...
    return Content(html, "text/html");
}

The request is as follows: http://localhost:37779/api/get/http:%2F%2Fwww.mysite.com But at some level, the application automatically replaces the double slashes with one.

Where is this going? Is there a way to prevent this behavior? Thank.
