forward : when forward is used server forwards the request to the new url and the control stays on the same page. in other words it just forward the request to new ur and come back fomr where forward is called.

sendRedirect : sendRedirect forward the request to url as new request and the cotrol goes to the destination page and never come back to the calling page

Send Redirect
when you use send redirect , it will rediredct the url to new url
and It will be displayed in browser
EX:
suppose u are in the page
http://162.0.0.1/submit.jsp and u r redircting url

response.sendRedirect(http://162.1.1.0/error.html);

then in browser url will changed and u will see error.html

Forward
When you use forward it will forward to particular page but in browser forwarded url won't dispaly
<jsp:forward page="http://162.1.1.0/error.html)" />

In browser u will see same url but it is the error.html page

Hi

The main difference is by using forward we can't forward the resource availble in other webserver / applicationserver .but by using sendRedirect we can achieve that.

Forward will dispatch the request to a particular resource and the output is displayed based on that file. Whereas sendRedirect allows a round trip to generate a new request from the browser to the target page

When the sendRedirect( ) method is invoked, it causes the web container to return to the browser a response indicating that a new URL should be requested. Because the browser issues a completely new request, any objects that are stored as request attributes before the redirect occurs will be lost. This is one of the biggest differences between a forward and redirect.

In response.sendRedirect we have to give the absolute path of the url and also rerequest and response objects will be send to the new page automatically .But in forward method we have to pass request and response objects to the new page explicitly.

forward() passews the request to the destinationj url that should be within the servletContext where as response.sendredirect passes to the destination url whether on the same domain or some other domain.

in sendRedirect we can forward the request to the file in another context path but in case of forward() method it only invokes the file within the context path....

Hi,

The forward action allows the request to be forwarded to another resource (servlet/jsp/HTMl> which are available in the same web-application (context).
Where as in the case of Response.sendRedirect() the request to be forwarded/redirected to another resource in the same web-application or some other web-application in the same server, or to a resource on some other web-server. The key difference is by using <jsp:forward> single request from a browser can process multiple resources. Where as by using SendRedirect() multiple requests take place in order to process multiple resources.
