Differences between two JSP page Jump Methods

Differences between two JSP page Jump Methods

 

Method 1: Responst. sendredirect ("testjsp "); The first method is to jump to the test. jsp page. Parameters in the session range can be passed, but the request parameters cannot be passed. Method 2: Request. getrequestdispatcher ("test. jsp"). Forward (request, response ); The second method is to pass both the session parameter and the request parameter. Add the parameter request. setattribute ("parameter", "avalue") to the request "); Obtain parameters on the target page: String value = request. getattribute ("parameter") = NULL? "": (String) request. getattribute ("parameter ");
