Sometimes we get short URLs that redirect to the actual file.

When the URL linked to a webpage rather than a binary, I had to not download that file and just keep the link as is.

To solve this, what I did was inspecting the headers of the URL. Headers usually contain a Content-Type parameter which tells us about the type of data the url is linking to. A naive way to do it will be -. It works but is not the optimum way to do so as it involves downloading the file for checking the header.
