thumbor uses a result storage to improve the speed of responding subsequent requests for the same image.
When a request for a given image with a set of parameters arrive, thumbor processes the request and before returning it, asks for the result storage to store it.
The next time the same request arrives, it will get it from the result storage and return it, thus saving a lot of processing.

allowed to specify an expiration, though, using the
RESULT_STORAGE_EXPIRATION_SECONDS configuration. Again, as the name
implies, it specifies the number of seconds with which files expire.
To use it you should set the
RESULT_STORAGE configuration to
