What is the reason for the Directory Listing Denied to appear on the website?

If you are prompted to visit the website: Directory Listing Denied This Virtual Directory does not allow contents to be listed.

This prompt means that the default home page is not found in the directory you specified, for example, you can directly enter the domain name. Space, but the above tips, please check whether there are index.htm, index.html, index.asp, default.asp, default.htm and other default home pages in the www directory. After the virtual host is opened, the default default home page is generated by default, which are index.asp, index.aspx, default.asp, deault.aspx, index.htm, etc., and your home page must be one of the above default homepages. This will automatically find the file.
