forward() method send source prg to target web resource prg
in same web application.and use source and target web
resource prg are use same req,res objects so will use data
in target web resource prg.
rd.forward(req,res)
sendRedirect() method send source web resource prg to target
web resource prg in same webapplication or two different web
applications in same server or different servers.and this
method will not use same req,res objects so if you want to
send data source to target web resource prg use query
string.
r.sendRedirect("srv2"?a=10);

Foward action is done at server site without interference of
web browser even the old URL is not changed whereas request
is forwarded to new resource hence forward action is faster
than redirect action. when forward operation is performed
request attributes and session attributes persists.
In case of redirection. servlet container sends the
response to clien web browser by setting status to
HttpServletResponse.SC_TEMPORARY_REDIRECT and location
header
to the new URL address where browser will have to redirect
new request automattically without interference of client.
when browser redirect new request to resource, the URL in
web browser changed. This proccess is slower than forward
because server send response to browser telling that
resource requested is moved temporary to other resource and
need redirction and then browser take action. The request
paramters are persist in new redirect request.

i will tell the conclusion of all
1. in case of forword() server will not inform client
2. in case of forword the same request will be sent to other
resourse so that request attribute will not distroy.
the opposite is for sendRedirect.
