Site-wide Compression
This setting enables automatic compression of responses to your users. There are multiple compression algoriths available that can be enabled. If you enable multiple types, we will prioritize in this order: Zstd, Gzip, Brotli.
All major browser engines support all compression algorithms:
| Browser | Zstd Support | Gzip Support | Brotli Support |
|---|---|---|---|
| Chrome | Since v123 | Since Release | Since v50 |
| Firefox | Since Firefox 126 | Since Release | Since Firefox 44 |
| Safari | Since 26.3 | Since 3.1 | Since 11 |
Caching
Bypass Cache
You can disable caching for your site if desired, and our servers will not cache response data at all.
Bypass does not affect cache headers Our servers will not cache response data, but they will still pass cache headers to client browsers, which may still cache the data locally.
Override Default TTL
You can manually set a cache TTL for all cachable site responses. This will override the received cache control headers.
Cache Purge
You can manually purge all cached responses of your site from our network caches.
High requests after purge As you might expect, purging the cache forces the next user request to be fulfilled from your origin. There may be a large number of upstream requests directly following a cache purge.
Image Proxy
Feature in Beta The Image Proxy is still in beta. We do not recommend enabling this in production yet.
You can automatically modify and optimize images while they are being loaded by your end user. Enabling this allows you to rewrite the URLs you use for images to a new Optimized Image URL, a different subdomain to call in your images from. By using the Optimized Image URL, JPEGs, PNGs, and GIFs loaded in can be compressed and optimized for web automatically. Additionally, by manually changing parts of the URL, you can crop and customize the image.
Manually Changing URLs
You can customize images being loaded in by enabling the Image Proxy and then changing the way that you reference images on your website in your HTML.
If your image tag calls in an image, e.g. mysite.com/images/picture.jpg you can change this to img-cdn.mysite.com/images/picture.jpg. By default, JPEGs and PNGs will be reduced to 80% quality.
| Option | Affect |
|---|---|
| 250x | Resize image to 250px wide |
| x500 | Resize image to 500px height |
| 0.20x | Resize image to 20% of original width |
| 50 | Crop to 50px square |
| 300x600 | Crop image to 300px x 600px |
| 50,fit | Scale to fit 50px square |
| r90 | Rotate 90 degrees |
| fv | Flip image vertically |
| fh | Flip image horizontally |
| png | Convert image to PNG format |
| q60 | Reduce image quality to 60% of original |
You can also combine options together, e.g. 250,fit,png which would scale to fit a 250px square and convert the image to a PNG format.
To use these settings, you would change the URL you’re using to call the image: img-cdn.mysite.com/250,fit,png/images/picture.jpg
Automatic Optimization
Once you enable the Image Proxy, you can optionally select different file formats that should be optimized automatically. We will rewrite the URL in responses to your site to use the image proxy with a 20% reduction in quality and other optimizations to make the image more web-friendly and fast. There is little to no visual impact on the detail of the images.
