Hi,

I want to check whether a CRL file is being updated regularly. In principle, I could set up an uptime monitor and check the value under “Headers” \> “Last-Modified”. But how can I set it up so that I’m notified if the “Last-Modified” value is still the same as it was during the last check?

@badge Yes, this is definitely something you can achieve with Distill. To guide you more accurately, could you please share the CRL URL you are planning to monitor?

Once we have that, we can check how the response is structured (headers/content) and suggest the best way to configure the monitor so you get notified when the Last-Modified value does not change.
