I use a third-party application that requests a config file from their Internet site. That file is out of date, but I can create my own file with the updated information.
How can I redirect any requests coming from my computer for a specific URL to a different file? For example, if any application requests 'http://www.theirsite.com/path/to/file.html', cause it instead to receive 'http://www.mysite.com/blah.html' or 'C:\My Documents\blah.html'?
