Subject Re: Redirect from CGI servlet
Date Tue, 20 Dec 2005 21:31:00 GMT
Good Afternoon Bob-

I found an asnswer here
http://archives.java.sun.com/cgi-bin/wa?A2=ind9811&L=servlet-interest&F=&S=&P=94953
to quote
"When most browsers receive a reply with status 302 (Moved Temporarily), they
look at the Location header, and automatically call the page specified there.
However, as I have found, if the URL of the page _to_ which you are redirecting
is the SAME as the page _from_ which you have sent the redirection, 
the browser assumes you are in a redirect loop.  
It then displays the message instead of auto-redirecting"

tack on a querystring  to the new URL tells the browser that you are not in a 'redirect loop'
Anyone else?
Martin-
