[Feature Request] Allow specific domains/records to bypass cache #928

Closed NebulaMods closed 3 months ago

NebulaMods commented 4 months ago

It would be cool if Technitium could disable caching for a specific domain, record, or even zone.

This came to my mind for doing ACME DNS challenges for wildcard certificates, cache can cause some issues on the TXT records. So having the ability to whitelist said record, would make things simpler, and Adguard Home also has this ability if I am not mistaken.

I set the TTL for this to 0 for this reason. Only for this records. Stops clients and others caching it.

Thanks for the request. Adding such an option will actually be too complex to add and configure. Instead, I would suggest that you use the HTTP API to delete cache for specific domain name in your cert renewal process/script. You will need to generate a auth token from the admin panel to use with that HTTP GET call.

Ah, this is smart. I didn't think of that.

Oh okay, thanks for the tip.
