Examples of org.mortbay.jetty.Request

org.mortbay.jetty.Request
Jetty Request.
Implements {@link javax.servlet.HttpServletRequest} from the {@link javax.servlet} package.

The standard interface of mostly getters, is extended with setters so that the request is mutable by the handlers that it is passed to. This allows the request object to be as lightweight as possible and not actually implement any significant behaviour. For example
- The {@link getContextPath} method will return null, until the requeset has been passed to a {@link ContextHandler} which matches the {@link getPathInfo} with a contextpath and calls {@link setContextPath} as a result.
- the HTTP session methods will all return null sessions until such time as a request has been passed to a {@link org.mortbay.jetty.servlet.SessionHandler} which checks for session cookiesand enables the ability to create new sessions.
- The {@link getServletPath} method will return null until the request has beenpassed to a {@link org.mortbay.jetty.servlet.ServletHandler} and the pathInfo matchedagainst the servlet URL patterns and {@link setServletPath} called as a result.
A request instance is created for each {@link HttpConnection} accepted by the server and recycled for each HTTP request received via that connection. An effort is made to avoid reparsing headers and cookies that are likely to be the same for requests from the same connection. @author gregw
