The first parameter to each of the “add” methods is an appropriate string value, response -> CSP -> reportOnly ( false ) // specify the origin to use if none provided for a directive $this -> response -> CSP -> setDefaultSrc ( '' ) // specify the URL that "report-only" reports get sent to $this -> response -> CSP -> setReportURI ( '' ) // specify that HTTP requests be upgraded to HTTPS $this -> response -> CSP -> upgradeInsecureRequests ( true ) // add types or origins to CSP directives // assuming that the default treatment is to block rather than just report $this -> response -> CSP -> addBaseURI ( '', true ) // report only $this -> response -> CSP -> addChildSrc ( '' ) // blocked $this -> response -> CSP -> addConnectSrc ( ', false ) // blocked $this -> response -> CSP -> addFontSrc ( '' ) $this -> response -> CSP -> addFormAction ( 'self' ) $this -> response -> CSP -> addFrameAncestor ( 'none', true ) // report this one $this -> response -> CSP -> addImageSrc ( '' ) $this -> response -> CSP -> addMediaSrc ( '' ) $this -> response -> CSP -> addManifestSrc ( '' ) $this -> response -> CSP -> addObjectSrc ( '', false ) // reject from here $this -> response -> CSP -> addPluginType ( 'application/pdf', false ) // reject this media type $this -> response -> CSP -> addScriptSrc ( '', true ) // allow but report requests from here $this -> response -> CSP -> addStyleSrc ( '' ) $this -> response -> CSP -> addSandbox () ![]() For more information, you shouldĬlass holds a number of methods that map pretty clearly to the appropriate header value that you need to set.Įxamples are shown below, with different combinations of parameters, though all accept either a directive Is served by the same domain ( ), it is very simple to integrate.Īs this is a complex subject, this user guide will not go over all of the details. For many simple sites, though, where all content This sounds complex, and on some sites, can definitely be challenging. This whitelist is created within the response’s Content-Security-Policy header and has many The browser will refuse content from sources that don’t meet Including images, stylesheets, javascript files, etc. This forces you to whitelist every single source of content that is pulled in from your site’s HTML, One of the best protections you have against XSS attacks is to implement a Content Security Policy on the site. The etag and last-modified options to their appropriate header. While most of the options are applied to the Cache-Control header, it intelligently handles ![]() You are free to set all of the options exactly as you need for your specific The $options array simply takes an array of key/value pairs that are, with a couple of exceptions, assigned To set the Cache values to what you need, through the setCache() method: The options and exactĬircumstances are too varied for us to be able to create a good default other than turning it off. Introduction to all of the cache headers power, but you can get a good understanding over atīy default, all response objects sent through CodeIgniter have HTTP caching turned off. ![]() This guide is not the proper place for a thorough This are handled through the Cache-Control and ETag headers. To contact the server at all since nothing has changed. This can lead to a huge performance boost to your application because it will tell the client that they don’t need HTTP Caching īuilt into the HTTP specification are tools help the client (often the web browser) cache the results. ![]() To be passed through all after filters before being sent to the client. The response object MUST be returned for the download to be sent to the client.
