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). Every time a browser connects to an HTTPS website, it contacts the OCSP responder specified in the SSL certificate, and asks if the certificate is revoked. If the respond er replies that the certificate is revoked, the browser blocks the page from loading.
What is a cipher suite? Cipher suites decide how secure, compatible and fast your HTTPS website is. A cipher suite is a set of information that helps determine how your web server will communicate secure data over HTTPS. A web server uses certain protocols and algorithms to determine how it will secure your web traffic. These are the ingredients of a secure connection. A cipher suite is essentially a list of those ingredients.

RewriteBase Directive Description: Sets the base URL for per-directory rewrites Syntax: RewriteBase URL-path Default: None Context: directory, .htaccess Override: FileInfo Status: Extension Module: mod_rewrite RewriteBase is used to fix cases where mod_rewrite is running in a per-directory context (Directory or .htaccess ) There it will act locally, i.e., the local directory prefix is stripped at this stage of processing and your rewriting rules act only on the remainder. At the end it is automatically added back to the path.
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. If the pattern is found in the URL, and the proper conditions are met, the pattern is replaced with a provided substitution string or action. This process continues until there are no more rules left or the process is explicitly told to stop.
