Question Submitted By :: Deepa I also faced this Question!!     Rank     Answer Posted By        Re: What is the difference between sendRedirect() and forward()? in what situations do we have to use send redirect() instead of forward(). Answer # 1    sendRedirect() means it's client side redirect at that time new parameters can be added.(i.e HttpRequest, HttpResponse)   forward() meand it's server side redirect at that time same parameters can be used.     forward() can be used forwarding the request from one servlet to jsp.(i.e with in the container).   redirect() can be used redirecting the one jsp to another jsp(i.e different containers).     0     Ajay        Re: What is the difference between sendRedirect() and forward()? in what situations do we have to use send redirect() instead of forward(). Answer # 2    When we use forward, then servlet container forwards all request to the target page. but in the case sendRedirect, container makes a new request to the target Page. So in forward , url link doesn't change but in sendRedirect url line change . Because container makes a new request, sendRedirect is much slower than forward.   If a target page has no relation with current page , then we can use sendRedirect(I think so....)     0     Bindhu Solomon        Re: What is the difference between sendRedirect() and forward()? in what situations do we have to use send redirect() instead of forward(). Answer # 3    forward() is a action element in jsp. it is used to pass ctrl from current page to another jsp page and it is a method in jsp.   send redirect() is a method in servlet. there are two methods used. as HttpServletResponse.encodeReDirctURL().which takes String represents a redirction url.next sendredirect() method. which takes the String returned from the encoderedirectString() and send it back to the client for redirection     0     Aravind        Re: What is the difference between sendRedirect() and forward()? in what situations do we have to use send redirect() instead of forward().
