Hi, I have turned off trailing slashes off.

However they still appear on the main domain name. when there is no sef url.

How do I turn it off for the main domain home page too?

Hi,

As far as I know this is not possible as the trailing slash after main domain is handled by web browser. You can check for example that Chrome and FireFox don't display trailing slash after the main domain, but Internet Explorer does.
However, both ways are treated the same by the web server, because the HTTP request for main domain always uses / as the requested path.
According to Google itself (see googlewebmastercentral.blogspot.co.uk/20...or-not-to-slash.html):
"Rest assured that for your root URL specifically, example.com is equivalent to example.com/ and can’t be redirected even if you’re Chuck Norris."

ok so why does it work on the site I have on joomla 1.5 with sh404sef?

and the site on joomla 2.5 + with artio sef does has the trailing slash?

I don't know. It can be different in the link itself in the website's source code, but there's no difference for Google and for your web server. JoomSEF doesn't offer an option to customize this for your root URL.
