The header also allows you to control the default file name. For static content you can manually configure the additional header in your web server. Usually content needs to expire immediately or be cached forever. You can see here in HttpWatch we have set up a far futures Expires value and set Cache-Control to public :. This allows future downloads of the file to be delivered from the local browser cache or an intermediate proxy. Here we go. We will update the final promise.

Here we have updated the final promise. Here is a working and more advanced example of this application on Codepen :. We will add some code to the end of the load event listener of the img object, to allow us:.

Here is a working example of this application on Codepen :. While there could be a lot to pick from this tutorial, it is glaring that Web APIs have a lot to offer as regards building powerful apps for the browser.

First, if someone discovered the direct link to the PDF file, he or she can access it directly without the PHP getting in the way. Second, you'll need PHP protection for each file you wish to protect using this quick-and-easy approach.

To protect several files in this manner, it makes sense to name the protected file and the PHP file with the same name, differing only in the extension, to keep everything straight. Actively scan device characteristics for identification. Use precise geolocation data. It turns out, however, that there is no way to do this; there is simply no way to intercept that request and modify it before it gets sent.
