Clear cache

You may need to clear the cache if the content on the source has updated or the data is not displaying correctly.

The cache can be spot clean or clean all.

The clearing time depends on the number of files and can take up to 15 minutes. A request to clear the cache can be made no more than once per minute.

Clear cache selectively

  1. В control panels go to CDN → CDN resources.

  2. Open the CDN resource page → tab Cache management.

  3. Open the card Clearing the cache.

  4. Select the type of cleaning Selective.

  5. Enter the paths to the files you want to delete from the cache. Enter a relative path (without the resource name), with the following characters at the beginning of the path * or /. Symbol * replaces any number of characters. Specify each path as a separate line, no more than 10 paths in one request.
    You can specify a specific file, directory or group of files with the same extension in the same path, to do this use query syntax.

    Example of a request:

    /path/to/file.jpg
    */directory/*.jpg

    The request will delete the file file.jpg in the specified directory, as well as all files jpgwhich are contained in the directory directory and its child folders.
