Caching and ScanEx configurations are no longer recommended by OPSWAT, but may be used under certain circumstances. Please contact OPSWAT customer support (https://www.opswat.com/support#support-levels) before using one of these methods.
There is no caching needed in the workflow API, because each process request is treated as new. There are a lot data processing in the workflow (e.g., file analyze, data sanitization, etc.). The workflow covers all ScanEx functions as well.
