Special Considerations for Forward Modify Path

When applied to Image and Video Manager requests, the Forward Modify Path behavior creates different cache keys for the derivative and pristine videos.

To purge both versions, submit a second URL with a query string parameter that disables Image and Video Manager (?imbypass=true).

In this example versions of product123.mp4 and product456.mp4 are now available on your origin. The Image and Video Manager rule that processes these video requests contains the Forward Modify Path behavior.

Submit a purge request containing the following URLs:

https://www.example.com/videos/product123.mp4?imbypass=true
https://www.example.com/videos/product456.mp4?imbypass=true
https://www.example.com/videos/product123.mp4
https://www.example.com/videos/product456.mp4
Purging the first two URLs clears the old pristine videos from the cache. Purging the second two URLs clears the derivative videos.
Important: To purge both versions, you must submit a purge for the pristine videos before purging the derivative videos.
