Provides access to various objects, including servletContext, session, request, andresponse.pageScopeMaps page-scoped variable names to their values.requestScopeMaps request-scoped variable names to their values.sessionScopeMaps session-scoped variable names to their values.applicationScopeMaps application-scoped variable names to their values.paramMaps a request parameter to a single String parameter value (obtained by callingServletReqwuest.getParameter(String name)).paramValuesMaps a request parameter name to an array of String values for that parameter name (obtained by callingServletRequest.getParameterValues(String name)).headerMaps a request header name to a single String header value (obtained by calling ServletRequest.getHeader(String name)).headerValuesMaps a request header name to an array of String values for that header (obtained by callingServletRequest.getHeaders(String)).cookieMaps a cookie name to a single Cookie object. Cookies are retrieved according to the semantics ofHttpServletRequest.getCookies(). If same name is shared by multiple cookies, an implementation must use thefirst encountered in the array of Cookie objects returned by the getCookies() method. However, the ordering ofcookies currently unsspecified in the Servlet specification.initParamMaps a context initialization parameter name to aString parameter value (obtained by callingServletContext.getInitparameter(String name)).
