Overview
CIMcloud uses a Content Delivery Network (CDN) to deliver your website’s images and static content quickly and efficiently to customers around the world. The CDN caches content at edge locations globally, reducing load times and improving the overall performance of your customer sites.
There are two versions of the CIMcloud CDN:
- CDN v1 (cloudfront.net) – CIMcloud’s older CDN that serves images in their original uploaded format.
- CDN v2 (cdn.cimcloud.com) – CIMcloud’s newest CDN which includes advanced automatic image optimization capabilities that improve website performance by automatically converting images to modern, efficient formats based on what each visitor’s web browser supports. Sites will be updated to CDN v2 during an upcoming version update. Early migration can be performed without requiring a full platform version update with CIMcloud’s assistance.
To determine which version a site is using, check the URLs of images.
Using The CDN
Uploaded images and documents are automatically published to the CDN. No additional steps are required.
Image Format Optimization
CDN v2 includes advanced automatic image optimization capabilities that improve website performance by automatically converting images to modern, efficient formats based on what each visitor’s web browser supports (avif, webp). The CDN detects the best image format based on info received from the user’s web browser and converts images on the fly to the new format.
Here’s an example product image:
-
- jpeg source image – 48.1 KB
- auto optimized – One of the formats below will be automatically used based on your browser’s settings:
- webp (optimized) – 25.9 KB
- avif (optimized) – 13.9 KB (the vast majority of users will receive this format)
Tips:
- Images must be in the /images and /gfx folders to be optimized
- Optimized images are cached in the CDN but the first several requests to a new image may be slower until the global caches are populated.
