CLI specific request building logic
Base class invoked from CLI rather than the webserver (Cron jobs, handling email bounces).
The content negotiator performs "text/html" or "application/xhtml+xml" switching. It does this through the public static function ContentNegotiator::process(). By default, ContentNegotiator will comply to the Accept headers the clients sends along with the HTTP request, which is most likely "application/xhtml+xml" (see "Order of selection" below).
Controllers are the cornerstone of all site functionality in SilverStripe. The {@link Director} selects a controller to pass control to, and then calls {@link handleRequest()}. This method will execute the appropriate action - either by calling the action method, or displaying the action's template.
A set of static methods for manipulating cookies.
A default backend for the setting and getting of cookies
Director is responsible for processing URLs, and providing environment information.
A class with HTTP-related helpers. Like Debug, this is more a bundle of methods than a class.
Invokes the HTTP application within an ErrorControlChain
Represents a HTTP-request, including a URL that is tokenised for parsing, and a request method (GET/POST/PUT/DELETE). This is used by {@link RequestHandler} objects to decide what to do.
Represents a response returned by a controller.
A response which contains a streamable data source.
Implements the "Null Object" pattern for a missing http request.
Handle the X-Pjax header that AJAX responses may provide, returning the fragment, or, in the case of non-AJAX form submissions, redirecting back to the submitter.
This class is the base class of any SilverStripe object that can be used to handle HTTP requests.
RequestProcessor deprecated
Middleware that provides back-support for the deprecated RequestFilter API.
Handles all manipulation of the session.
Generate URLs assuming that BASE_PATH is also the webroot Standard SilverStripe 3 operation


The Cookie_Backend interface for use with Cookie::$inst.
Indicator for a class which cannot handle requests directly, but is able to generate a delegate for those requests.
Interface that is implemented by controllers that are designed to hand control over to another controller.
RequestFilter deprecated
A request filter is an object that's executed before and after a request occurs. By returning 'false' from the preRequest method, request execution will be stopped from continuing


A {@link HTTPResponse} encapsulated in an exception, which can interrupt the processing flow and be caught by the {@link RequestHandler} and returned to the user.
