Iis 404 settings and 404 impact on websites

In some 2003 systems, iis cannot be set as above. Although the following method is acceptable, the returned status code is 200:
Set message content to url
Enter/404.htm in the url
Put 404.htm under the root directory of the website.

You cannot directly modify the default 404 page.

This is a question about file quota. You only need to set 404.htm to everyone readable.

Open iis Manager --> right-click website attributes --> Click Custom Error options --> select 404 --> Select and open edit attributes --> set to url --> enter in url "/ www.111cn.net.html "--> in" message type ", you must select" file "or" default value ", do not select "url". Otherwise, "200" status code will be returned. --> Definitely decompress the err.html page to upload it to the root directory of the website.
