/**
* Jetty Request.
*
* Implements {@link javax.servlet.http.HttpServletRequest} from the javax.servlet.http 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 behavior. For example
*
*
* - The {@link Request#getContextPath()} method will return null, until the request has been passed to a {@link ContextHandler} which matches the
* {@link Request#getPathInfo()} with a context path and calls {@link Request#setContextPath(String)} 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.eclipse.jetty.server.session.SessionHandler} which checks for session cookies and enables the ability to create new sessions.
*
* - The {@link Request#getServletPath()} method will return null until the request has been passed to a
org.eclipse.jetty.servlet.ServletHandler
* and the pathInfo matched against the servlet URL patterns and {@link Request#setServletPath(String)} called as a result.
*
*
* A request instance is created for each connection 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.
*
*
* 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.
*
