Example web server to demonstrate the difference between MIME types via Content-Type HTTP headers and file extensions. Learning target is that file extensions in an URI might not determine the MIME type of the delivered content.
As this module has no npm dependencies, you can simply clone this project. It is not published to npm.
Start the server via npm start. You can change the port in the package.json file or by using npm config set port [PORT]. Default is 8080.
The server provides two end points: /cat.jpg returns an HTML file while the inlined /cat.html results in the actual image file. For both URI the HTTP methods GET and HEAD are supported. All other requests return a 404 status code.
To extend both URI by a prefix you can npm config set base [PREFIX] or edit the package.json. Default is /.
The cat.jpg image file is public domain. The actual project is MIT-licenced.
