Subject Re: simple JSP redirect to another page -- how to deal with relative URLs
Date Fri, 25 Apr 2008 20:27:39 GMT
Never mind .. I saw your other responses and the best solution is the 
redirect option.  After following the redirect, the browser will have 
the correct URL for calculating the full url of each of the page's 
resources.
