Without using any plugins or software installation server side, is it possible to achieve true 301 redirects with IIS6? The hosting provider is has been unhelpful in this area. I've tried the system.webServer for web.config but this only works for IIS7.
I am now placing php headers on each (corresponding .html) page:
header("HTTP/1.1 301 Moved Permanently");
header("Location: http://website.com/page.php");
Is this effective enough for Google and other engines? Is there anything else I can do without having direct access to the server (only ftp and control panel). Or perhaps there is actually something the host provider can do that they don't know about? Please advise, I'd have already moved this site over to linux if I was able.
