Custom Error settings only picking up 404 on ASPX pages and not directories addresses or other file types such as .html

This is what I have in my web.config.  I'm using a remote host and only have FTP abilities.

     <customErrors mode="RemoteOnly">
       <error statusCode="404" redirect="/error_docs/Oops.aspx" />
     </customErrors>

Since .html files are not being interepreted by the .NET Compiler they would not be redirected on error.  If this is what you want then you would need to put the html pages in a .aspx or .ascx wrapper so that IIS will handle correctly.

Actually, given that dgelinas is looking for 404 error handling (which occurs when no file exists at the requested URL), there's nothing to wrap in ASPXs....

But Aeros is right: those customErrors settings will only affect errors that arise during (or during an attempt to call) a page/file that is part of the ASP.NET application, which includes any ASPX, ASCX, or related code (C# or VB) files, but does not include HTML files, non-.NET ASP files, etc.

So, if a user attempts to request a URL with a *.aspx extension, the handling of this request would be handed to ASP.NET, and ASP.NET could serve its custom errors.  But if a user attempts to request a URL with a *.html extension, this is not processed by the ASP.NET application, so no customErrors setting in the ASP.NET application would have the chance to come into play.

If you need to specifiy custom 404 error pages for your Web site or application, regardless of whether or not the requested URL is an ASP.NET application file, you'll likely need to do so within IIS itself.  In this case, go into your Internet Information Services Manager, find your Web site or Web application virtual directory, right-click and select "Properties".  Select the "Custom Error" tab, select the line for the HTTP error you wish to intercept (such as 404), then click "Edit Properties".  You can then set the Message Type to File and enter your own local static file to be used, or set the Message Type to URL and specify the URL to which all 404 errors should be redirected.  This will then take effect for all such errors that occur within that Web site or directory, regardless of the type of file being requested.
