javax.servlet.http.HttpServletRequest, javax.servlet.ServletRequestpublic class Request
extends java.lang.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.
If IOExceptions or timeouts occur while reading form parameters, these are thrown as unchecked Exceptions: ether RuntimeIOException,
BadMessageException or RuntimeException as appropriate.

This method is useful for creating redirect messages and for reporting errors.
