I have inherited an Umbraco 4.7.2 project. It redirects from /xxx urls to a sub-domain style url like xxx.domain for most of its sub-nodes, which is not ideal for our local and internal development site. Here are more details on the problem:

1. I have created a local IIS websites for it, called my-website.com.
2. In Umbraco back office, there is a sub-node with the name as xyz and the url as /xyz. there was a host name defined on that node as xyz.my-website.com and when I open opening my-website.com/xyz, it was automatically redirected to xyz.my-website.com.
3. I have removed this host name entry from the node and have restarted IIS, and now the only available URL for this node is /xyz.
4. Still, when I open my-website.com/xyz in the browser, it redirects to xyz.my-website.com.
5. There are no rewrite rules available in web.config or /Umbraco/urlrewriting.config files

Do you know the solution on top of your head? Thanks.
