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.
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.

, 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.

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