CDN for Joomla! uses the options below. Labels and descriptions follow the current English extension language strings. Rows marked as Pro are editable only in the Pro edition; Free either omits the control or keeps its documented fixed value.

Setup
| CDN Domain | Enter the CDN hostname without a protocol, for example cdn.example.com. Free uses the first valid hostname.Pro only: Enter a comma-separated list to distribute files across multiple CDN hostnames. Each file is assigned deterministically, so its CDN URL remains stable. Pro also supports the {subdomain}, {domain}, and {extension} placeholders for parts of the current site hostname. |
| CDN Protocol | Select the protocol for generated CDN URLs. Free follows the protocol of the current page. Pro can select the same protocol, http://, or https://.Options: Same, HTTP PRO, HTTPS PRO |
| Use Relative Protocol | Use a protocol-relative // URL when the selected CDN protocol matches the current page, instead of an explicit http:// or https:// URL.Options: No, Yes Pro only. |
| Site Domains | Select whether this CDN set applies to every site hostname or only to specific hostnames. Free applies its one CDN set to every site hostname. Options: All, Specific Pro only. |
| Specific Domains | Enter a comma-separated list of site hostnames on which this CDN set should be used. Do not include a protocol or path. Pro only. |
| Site Root | Enter the site folder connected to the CDN origin. This folder prefix is removed from the generated CDN path. Leave this at / when the complete site root is connected, or use a folder such as /images/. |
| Enable on Protocol | Select on which page protocols this CDN set is active. Free always runs on both HTTP and HTTPS pages and follows the current page protocol. Options: Both, HTTP, HTTPS Pro only. |
| File Types | Enter a comma-separated list of file types whose matching local URLs should be rewritten to the CDN hostname. |
| Ignore Files | Enter a comma-separated list of path or filename fragments to ignore. Matching URLs are left unchanged. |
| Enable in Inline Scripts | Convert matching file URLs found in inline JavaScript. Disable this if a particular script is not compatible with URL rewriting. Options: No, Yes |
| File Versioning | Add the local file modification time to eligible file URLs. This makes the origin-pull CDN request a new version after the local file changes. Only existing, safe site files with a selected file type are versioned. The required filesystem checks may add work while rendering the page. Options: No, Yes Pro only. |
| Versioning File Types | Enter a comma-separated list of file types to which file versioning should be applied. Pro only. |
