Super User is a question and answer site for computer enthusiasts and power users. It's 100% free, no registration required.

Is there a way to tell (as a client) if there is any server side code that's being processed (PHP/ASP.NET) or if it's simply static html files?

Do you mean besides looking at the file extension? –  Michael Itzoe Jun 25 '10 at 20:06
@Michael - Lots of websites use MVC frameworks that don't ever show an extension. Like superuser.com for example. –  MrChrister Jun 25 '10 at 21:27

Try builtwith.com, it will tell you everything it can find out about the platform the server is running on.

we can also use appInspector as additional resources. –  xK0nB1n Aug 21 at 9:57

You can't always know for sure. Here's an example why. I can set apache to handle a specific extension any way I want. I can have php render a .html document which contains PHP.

All the user will see is they are served an HTML document (.html extension).

For the most part though, the extension can give you a hint, but also if there's dynamic content that's a good clue.
