This class of status code indicates the client must take additional action to complete the request. Many of these status codes are used in URL redirection. [2]A user agent may carry out the additional action with no user interaction only if the method used in the second request is GET or HEAD.
In more detail, when making a TLS connection, the client requests a digital certificate from the web server. Once the server sends the certificate, the client examines it and compares the name it was trying to connect to with the name(s) included in the certificate. If a match occurs, the connection proceeds as normal.
The OCSP responder uses the certificate serial number to look up the revocation status of Alice's certificate. The OCSP responder looks in a CA database that Carol maintains. In this scenario, Carol's CA database is the only trusted location where a compromise to Alice's certificate would be recorded.
A certificate may be revoked before it expires, for example because the secrecy of the private key has been compromised. Newer versions of popular browsers such as Firefox, [32] Opera, [33] and Internet Explorer on Windows Vista [34] implement the Online Certificate Status Protocol (OCSP) to verify that this is not
If you're using broadband (cable) internet and you can't connect, try the following troubleshooting steps in the order listed until you get up and running again. 1.

The HPKP is not valid without this backup key (a backup key is defined as a public key not present in the current certificate chain). [4] HPKP is standardized in RFC 7469. [1] It expands on static certificate pinning, which hardcodes public key hashes of well-known websites or services within web browsers and applications. [5]
HSTS addresses this problem [2]: §2.4 by informing the browser that connections to the site should always use TLS/SSL. The HSTS header can be stripped by the attacker if this is the user's first visit. Google Chrome, Mozilla Firefox, Internet Explorer, and Microsoft Edge attempt to limit this problem by including a "pre-loaded" list of HSTS sites.
