Gumlet CDN can be used for all kinds of non-image files hosted on your original storage including mp4s, CSS, or JS. In our image optimization service, image files will be optimized when called with a Gumlet subdomain but non-image files, they will only be fetched and not optimized.
Instead, we will just transmit them through our CDN and you will get the advantage of fast delivery of those files and reduced latency.
These files can simply be served in the same manner as images. You must configure a web folder source with a Base URL of https://example.com, for example, your CSS file is located at https://example.com/css/main.css. You can serve the CSS file after setting up the source at https://example.gumlet.com/css/main.css. Your CSS file will now be distributed via our CDN. It’s that easy.
