If 'Cache on Disk' is not enabled in the web proxy settings, where is the data stored?

When 'Cache on Disk' is not enabled in the web proxy settings of MikroTik, the data is stored in RAM. This means that the cached data resides in the system's volatile memory, allowing for quick access and processing. Storing data in RAM provides faster retrieval times compared to disk storage, but it also means that this data will be lost when the system reboots or the power is turned off, as RAM does not retain information after the power is disconnected.

The option that suggests data does not get stored implies there would be no cache; however, without disk caching, it still utilizes RAM for temporary storage. The mention of a USB disk and a temporary disk also points to storage mediums that are not used when disk caching is disabled. Hence, the correct detail here revolves around the use of RAM for caching when disk storage is not utilized.
