Query regarding Response.sendRedirect

[Manish Jaju]

During response.sendRedirect, How client comes to know that it has to again make a new request. How that Information is sent to client(for making a new request). Can anybody clarify this.

It is the job of the developer to re-direct the browser to the new location.

At most, you can provide a link on the page where the client can click if the page doesn't get displayed automatically in, say, a few seconds.

When you call sendRedirect the server sends two header variables that tell the client's browser what to do:

The first is a 302 (Moved Temporarily) status code.
The other is the "Location" value containing the page to which the browser is to be redirected.

[B]HTTP/1.x 302 Moved Temporarily[/B] 
Server: Apache-Coyote/1.1 
[B]Location: http://127.0.0.1:8080/page2.html[/B]

hi i have a doubt when the user use SendRedirect(...newPage.jsp);
will the newPage.jsp will contain the data in req
Let me know the funtionality......
i mean data that we store in req while travesing the pages...

say if u have 4 pages while

page 1 ---> page2 ---> page3
due to some problem u are redirecting the client req so that req goes to new page...
while crawling the page1 thru page 3 if store data in req will i get in transfeed page

No, with sendRedirect, each page will have a new request object.
If you want to retain your objects across requests, you would need to bind them to session scope.
