This article describes why the webcache feature is not available on some models.
Scope
FortiGate x0 models.
Solution
When prompted to enable webcaching on a policy, check first if the FortiGate has a disk.
This is easily noted by the model number.
If it ends in 1, for example, FortiGate 1801F, then it has a disk. A FortiGate 1800F does not have a disk.
It will either be a disk toggle or require dual disks. This is dependent on the model.
The disk status can also be found in the CLI:
