Arne Blankerts theseer

Keybase proof

I hereby claim:

I am theseer on github.
I am theseer (https://keybase.io/theseer) on keybase.
I have a public key whose fingerprint is BEEB 9AED 51C2 8445 FAB1 4222 8DDB 46C4 EA2E BCDC

To claim this, I am signing this object:

If-Modified-Since, PHP CLI Server and Firefox

Explanation

When sending the cache control header Cache-Control: no-cache, must-revalidate along with a Last-Modified timestamp, the browser is required to send along an If-Modified-Since header for the next request to the same URL.

The server then is entitled to return HTTP/1.1 304 Not modified in case the content didn't change and the stored copy may still be used.

Sample Code

Caddy Server - First Contact

Offene Fragen nach der Session

Wie sieht es bei den Zertifikatserneuerungen aus?

Die werden ebenfalls automatisch durchgeführt, wenn Letsencrypt oder ZeroSSL - bzw eine ACME CA - im Einsatz ist. Kann man aber natürlich auch "klassisch" manuell machen, wenn man das aus irgendwelchen Gründen braucht.
