[…] The option [S=1] was changed to [S=1,R]. At first, I found that while Firebird happily changed the URL in the address bar from *.html to *.php, Internet Explorer did not. I suspect that the return code passed back to the browser was not 301 – Moved Permanently. Adding the “R” option seems to have solved that. Update 2006-10-03: 3 years on I’ve realized that “R” alone is not correct, one must also pass the “301″ code, otherwise, it redirects without sending the “Moved Permanently” code. I’ve corrected the code snippet above to reflect this. Sorry… […]
