I am trying to make a 404 handler for media, so far I have come up with this:

public class Media404Handler : INotFoundHandler
{
    private int redirectId;

    public bool Execute(string url)
    {
        var urlParts = url.Split('/');

        if (urlParts.Contains("media"))
        {
            var qs = HttpContext.Current.Request.QueryString.ToString();

            HttpContext.Current.Response.Redirect("/Assets/img/404.png" + (string.IsNullOrWhiteSpace(qs) ? "?" + qs : ""));

            return true;
        }
        return false;
    }


    public bool CacheUrl
    {
        get { return false; }
    }

    public int redirectID
    {
        get { return redirectId; }
    }
}

When I try to browse to /media/test404 it gets run like it should and redirects to /Assets/img/404.png, but if I browse to /media/test404.jpg nothing happens.

Is it just not possible to do this, or do I need to change the configuration somewhere?

Got it working with an IIS rewrite - doesn't send a 404 status code, though. But thats ok in my case.

<rewrite>
  <rules>
    <rule name="RewriteNonExistingImages">
      <match url=".((jpg)|(jpeg)|(png)|(gif))$" />
      <conditions>
        <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
      </conditions>
      <action type="Rewrite" url="/Assets/img/404.png" appendQueryString="true" />
    </rule>
  </rules>
</rewrite>

I'll add my tuppence to this, as I got this working with IIS error handling by configuring "/media/web.config" with:

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    <system.webServer>
        <handlers>
            <clear/>
            <add name="StaticFileHandler" path="*" verb="*" preCondition="integratedMode" type="System.Web.StaticFileHandler"/>
            <add name="StaticFile" path="*" verb="*" modules="StaticFileModule,DefaultDocumentModule,DirectoryListingModule" resourceType="Either" requireAccess="Read"/>
        </handlers>
        <httpErrors errorMode="Custom" existingResponse="Replace">
            <remove statusCode="404" subStatusCode="-1" />
            <error statusCode="404" path="/404/" responseMode="ExecuteURL" />
        </httpErrors>
    </system.webServer>
    <system.web>
        <customErrors mode="Off" />
    </system.web>
</configuration>

Where "/404/" is my Umbraco not found page.
