Subject Re: forward vs redirect ?
Date Mon, 01 Dec 2003 14:13:18 GMT
Thank u for the reply. I followed the same pattern in another non struts
based application. But on reading the struts users guide and articles and
going through the sample sapplication, I found that nobody is mentioning
about redirect and the problem with refresh. So I gott confused whether
there are other ways available.  The sample application is throwing an
exception, when the page displayed adding new subscriptions is refreshed.
