ORIGIN URL
Specify the HTTP URL of your back-end server on which you need to do caching. We can update origin url using edit button and click again to save it.
Add Custom Hostnames
Custom hostnames can be used instead of our default hdcdn.xyz hostname. After adding the hostname, create a CNAME record.
Cache Expiry Time
Configure cache expiry time after which cached data will be re-validated.
Disable Cookies
Enable this feature to strip all the Set-Cookie headers from the zone hostname. It also gives you a cookie less domain.
Vary Cache By
Enable Vary Cache to use each of the selected parameters as part of the cache keys. Each parameters combination stores its own separate cached file.
-
URL Query String : Enable this feature to use it as part of the caching key. For example, image.jpg and image.jpg?v=1 will be treated as two separate files.
-
User Country Code : Enable this feature to use the country code of the user as part of the caching key. Users from different countries will get different cached files.
-
Browser WebP Support : Enable this feature to use requesting user's support for WebP as part of the caching key. Browsers that support WebP will get different cached than browsers that do not.
Add CORS Header For
Enable this feature to automatically add CORS headers (Cross-Origin Resource Sharing) to all requests to files along with extensions from the list.
Add Canonical Headers
Enable this feature to automatically add a Canonical link header to your requests targeting to your origin URL. Perfect for SEO optimization.
Ignore Vary Header
Enable this feature to ignore the Vary header for the best possible Cache Hit Rate and Performance.
Forward Host Header
Ensure it remains disabled in most cases. Enable this feature to forward the original host header of the request to the origin server.
Purge
Purging a URL will remove the file from the CDN cache and re-download it from your origin server. Please enter the exact CDN URL of each individual file. Note: We don't support Wildcard values.
-
Purge Zone : Purges all the files cached in the zone.
-
Purge URL : Purges all the files specified in the URL input field.
