/** Jetty Request.
* <p>
* Implements {@link javax.servlet.HttpServletRequest} from the {@link javax.servlet} package.
* </p>
* <p>
* 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<ul>
*
* <li>The {@link getContextPath} method will return null, until the requeset has been
* passed to a {@link ContextHandler} which matches the {@link getPathInfo} with a context
* path and calls {@link setContextPath} as a result.</li>
*
* <li>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 cookies
* and enables the ability to create new sessions.</li>
*
* <li>The {@link getServletPath} method will return null until the request has been
* passed to a {@link org.mortbay.jetty.servlet.ServletHandler} and the pathInfo matched
* against the servlet URL patterns and {@link setServletPath} called as a result.</li>
* </ul>
*
* 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.
*
* <p>
* The form content that a request can process is limited to protect from Denial of Service
* attacks. The size in bytes is limited by {@link ContextHandler#getMaxFormContentSize()} or if there is no
* context then the "org.eclipse.jetty.server.Request.maxFormContentSize" {@link Server} attribute.
* The number of parameters keys is limited by {@link ContextHandler#getMaxFormKeys()} or if there is no
* context then the "org.eclipse.jetty.server.Request.maxFormKeys" {@link Server} attribute.
