/**
 * Content Security Policy (CSP) is an added layer of security that helps to detect and mitigate certain types of
 * attacks, including Cross Site Scripting (XSS) and data injection attacks. These attacks are used for everything from
 * data theft to site defacement to distribution of malware.
 *
 * CSP is designed to be fully backward compatible. Browsers that don't support it still work with servers that
 * implement it, and vice-versa: browsers that don't support CSP simply ignore it, functioning as usual, defaulting to
 * the standard same-origin policy for web content. If the site doesn't offer the CSP header, browsers likewise use the
 * standard same-origin policy.
 *
 * 
 * NOTE: This class has been automatically generated from the {@link io.vertx.ext.web.handler.CSPHandler original} non RX-ified interface using Vert.x codegen.
