Hi there,
I think both the functions take relative URLs instead of absolute URLs that
you are giving. So try using relative URLs.
You can set an attribute in "request" (not response) by setAttribute(String,
Object) method and then you can use <jsp: forward> tag to go to the other
page. Unlike sendRedirect() your request would not be reset and you would be
able to get the value of your attribute.
regards
Y
