Where is the page of "HTTP Error 404.0 - Not Found"

Question

User-1361715659 posted

Hi,

When I try to view a broken static file in my website, I get the error page titled "HTTP Error 404.0 - Not Found"
URL: https://www.xtopia.io/ss.img

How do I overwrite this setting or change the file itself?

I found the 404 file at C:\inetpub\custerr\en-US but it is not actually the same file.


I also try in web.config as below but it shows "The page cannot be displayed because an internal server error has occurred.":
<httpErrors errorMode="DetailedLocalOnly" existingResponse="Auto">
<remove statusCode="404" />
<error statusCode="404" responseMode="ExecuteURL" path="404.htm" />
</httpErrors>

Thanks.

Look at this blog. This is how you add your custom error page.

Hi huislaw,

As far as I know, the customErrors tag only works for the server pages not for static files(js or image).

So you will find it show the 404.html page not aspx error page.

I suggest you could use httperrpr instead of custom error.

You could opne the iis console manager and find the error pages acion.

More details, you could refer to below image:

More details about how to enable the httperror in web config, I suggest you could refer to below aritcle.

Thanks.
I managed to handle static files such as .js and .img.

https://www.xtopia.io/nothispage - OK

https://www.xtopia.io/nothispage.aspx - OK

https://www.xtopia.io/nothispage.js - OK

https://www.xtopia.io/WebResource.axd  - Not OK

But now I noticed the axd file still cannot be handled https://www.xtopia.io/WebResource.axd 

How can I solve this?

Thanks.

Hi huislaw,

As far as I know, the WebResource.axd an HTTP Handler that is part of the .NET Framework that does one thing and one thing only – it is tasked with getting an embedded resource out of a DLL and returning its content. 

So it will not go to the custom error page. It will only work with httphandler exception.

Here is a workaround, I suggest you could use url rewrite to to directly redirect the WebResource.axd to 404 error page.

More details, you could refer to below url rewrite setting.

<system.webServer>
        <rewrite>
            <rules>
                <rule name="test" stopProcessing="true">
                    <match url="WebResource.axd" />
                    <action type="Redirect" url="http://localhost:4568/" />
                </rule>
            </rules>
        </rewrite>
  </system.webServer>

Result:

Hi,

The WebResource.axd is needed for 3rd party component, so we cannot redirect it.

Is there other way to solve this?

Thanks.
