even stranger is that on Mozilla and Chrome it doesn't show the default browser page for 404 http error, but in IE11 it does show the page not found message of the web browser

We will check the issue and get back to you.

Thanks

We have fixed this issue, fix will be pushed with the new release (few days).

Thanks

khorvat, hello,
 

Can you share solution for us ? We have sam problem on our site; if  you type www.mydomain.com/something
 

 if (something is not meaning or not match any url ,  Can we redirect it homepage ? Default.aspx )

at http://social.clipflair.net we had fixed that (e.g. try http://social.clipflair.net/somepage)

judging from the version control at http://clipflair.codeplex.com, I think you need the following at web.config (search for the respective sections)

    <!-- indicates if error page should show detailed error message output for non administrator users -->
    <add key="ShowDetailedErrorsForNonAdmin" value="False" />

and also make sure you have this

    <!--<httpErrors existingResponse="PassThrough" />-->
    <httpErrors errorMode="Custom" existingResponse="Replace">
        <remove statusCode="404" subStatusCode="-1" />
        <error statusCode="404" path="/ErrorPages/404.aspx" responseMode="ExecuteURL" />
    </httpErrors>

you can also grab our web.config from http://clipflair.codeplex.com/SourceControl/changeset/view/07b7f3c138b8#Server/ClipFlair.Social/web.config and use WinDiff or CodeCompare to compare with yours. Mind you though we're using MonoX v4.9.40.4845, so it might not be a total match in available entries with yours if you use different version of MonoX

It's works. perfecti thansk you very much
