Hide IIS version when user gets error HTTP Error 404.0 - Not Found and view source file from webbrowser

Question

When user load the page with wrong url or type wrong path to the file in url then user get error with below message in web browser.

" HTTP Error 404.0 - Not Found The resource you are looking for has been removed, had its name changed, or is temporarily unavailable."

Now if user right click and select View Page Source from the context menu then user can see IIS version in response headers. This is for IIS 10

Is there any way to hide IIS version title tag.

Hi @Mehul Donga,

Is there any way to hide IIS version title tag.

Usually we can remove the IIS version with removeServerHeader in system.webServer/security/requestFiltering. But the content mentioned in your question is caused by errorMode="Detailed".

You can view the basic error pages in Error Pages, like these:

After the above configuration, the IIS server will generate other information (including the content of the header/title) in Response section of browser devtools.

So if you need to hide this part of the content, you need to use a custom error page (or use errorMode="DetailedLocalOnly").
