The easiest way to understand this is to think about how a browser sees a relative link. Browsers don't know that they're dealing with a servlet app. A sendRedirect simply puts the following header in the response: "Location: url"
Let's take the following url: http://www.mydomain.com/cal/index.jsp If your page "index.jsp" resides in the context root "cal" and you want to send a redirect to "page2.jsp" you would use "page2.jsp". This tells the browser to look in the current directory for a file name "page2.jsp". If you enter "/page2.jsp" The browser will go to what IT considers to be the webroot; the first directory after the base url "http://www.mydomain.com/"; and look for "page2.jsp". If you're several directories below the context root and need to redirect to a higher directory, you're better off prepending one "../" to the url for each directory that you need to climb than to try to list the context root and work your way down (" /cal/page.jsp"). This way, you won't need to fish through your code and change the urls if the application name "cal" changes. But that's just my opinion. -Ben On Friday 05 September 2003 02:07 pm, Charlie Toohey wrote: > The Servlet API doc for the sendRedirect method states: > > "....If the location is relative with a leading '/' the container > interprets it as relative to the servlet container root....." > > I've looked thru the Servlet Spec and can not quite figure out what they > mean by servlet container root ?
