OCSP Stapling on Nginx and Apache webserver To understand OCSP stapling, it is necessary to understand OCSP, the Online Certificate Status Protocol. OCSP is a protocol for determining whether a certificate is revoked (for instance, becau se its private key was compromised).

apache mod_rewrite module guide - part 1 mod_rewrite is an Apache module that allows for server-side manipulation of requested URLs. Incoming URLs are checked against a series of rules. The rules contain a regular expression to detect a particular pattern.
