public class Request extends Object implements javax.servlet.http.HttpServletRequest
Implements 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
getContextPath() method will return null, until the request has been passed to a ContextHandler which matches the
getPathInfo() with a context path and calls setContextPath(String) as a result.SessionHandler which checks for session cookies and enables the ability to create new sessions.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 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.
Request instances are recycled, which combined with badly written asynchronous applications can result in calls on requests that have been reset. The code is written in a style to avoid NPE and ISE when such calls are made, as this has often proved generate exceptions that distraction from debugging such bad asynchronous applications. Instead, request methods attempt to not fail when called in an illegal state, so that hopefully the bad application will proceed to a major state event (eg calling AsyncContext.onComplete) which has better asynchronous guards, true atomic state and better failure behaviour that will assist in debugging.
The form content that a request can process is limited to protect from Denial of Service attacks. The size in bytes is limited by
ContextHandler.getMaxFormContentSize() or if there is no context then the "org.eclipse.jetty.server.Request.maxFormContentSize" Server
attribute. The number of parameters keys is limited by ContextHandler.getMaxFormKeys() or if there is no context then the
"org.eclipse.jetty.server.Request.maxFormKeys" Server attribute.

Request instance of a ServletRequest, by
coercion, unwrapping or special attribute.request - The requestRequest instance of a ServletRequest.public HttpFields getHttpFields()
public HttpFields getTrailers()
public HttpInput getHttpInput()
public boolean isPush()
public boolean isPushSupported()
public PushBuilder getPushBuilder()
getQueryString()
getRequestedSessionId() value, unless at the time
of the call getSession(boolean)
has previously been called to create a new HttpSession, in
which case the new session ID will be used as the PushBuilders
requested session ID.getRequestURL()
plus any getQueryString() HttpServletResponse.addCookie(Cookie) has been called
on the associated response, then a corresponding Cookie header will be added
to the PushBuilder, unless the Cookie.getMaxAge() is <=0, in which
case the Cookie will be removed from the builder.PushBuilderImpl.isConditional() header is set
to true.
Each call to getPushBuilder() will return a new instance of a PushBuilder based off this Request. Any mutations to the returned PushBuilder are not reflected on future returns.

Because this method returns a StringBuffer, not a string, you can modify the URL easily, for example, to append path and query parameters.
This method is useful for creating redirect messages and for reporting errors.
