PixelBin follows some pre-determined rules regarding the caching of the transformed and original files.
- When utilizing PixelBin Storage to store and deliver files, the original versions of the files are kept there permanently.
- PixelBin has no control over the original copies of the files when it uses your server or storage as a datasource to deliver files.
- PixelBin caches the files at two levels: PixelBin's internal cache and at the CDN.
- For PixelBin's internal cache when a file is requested via a CDN URL, there are two scenarios depending on the storage used.
- If PixelBin Storage is used, then both the original and transformed versions of the file are typically stored indefinitely.
- If external storage is used, then only the transformed file is stored. This ensures that there are fewer requests made to your server or storage for a specific transformation.
- PixelBin caches a copy of every original and transformed file at the CDN regardless of whether the original copy is kept at PixelBin Storage or external storage. The CDN caches each URL for a maximum of
six hours.This is done to ensure quick delivery of your files.
