It might be a virtual directory pointing to a physical directory. If you enter http://www.deal-eh.ca/ajax/, you will see your site, but no stylesheet is loaded, also no AJAX features, which makes me think that /ajax is pointing back to your site.

If you are very sure that you don't have a directory called "ajax", then it must be a virtual directory. If you have access to the IIS, you will be able to see it in your IIS. Basically, a virtual directory is a directory you created in IIS, and it can point to a physical directory. My guess is that somehow you created "ajax" virtual directory and pointed to your web application, that is why when you access http:// www.deal-eh.ca/ajax/, it will load data from your web application, it is like a link.

How to prevent it?
Just remove the virtual directory from IIS.

Hi
I still don't find in my IIs the virtual directory Ajax.
Is there a way it is part of the Ajax installation that is created automatically?
Thankyou

Hi,
I think I understand what is going:
first I don't have any subdirectory of AJAX
The link you showed me is an error page that I have when the page is not found but becuase
of an error the css was not displayed. And I think that the reason I got links to this address is from
hackers. But I might be wrong and this is why I am checking it.
Thankyou
