Set .ashx as start "page" for web application

Is it possible to set an .ashx file as the starting (or default) page for a web application? If so, how is it done?

Edit - Some good suggestions. I have added "Default.ashx" to the IIS Default Documents and "Enabled Default Document" on the website, however, it only displays a directory listing even though I have disabled directory browsing.

Any other suggestions would be appreciated. (IIS Version 5.1)

Edit - Restarted IIS and it works.

Question - May I also ask if it is possible to set the start page to an .ashx from within Visual Studio 2005? I can't seem to debug from within Visual Studio after doing this.

Answer - In the Application Properties a "Start Action" can be selected under the "Web" tab. In fact, it also allows the selection of which Server/Port and Debugger to use. Very cool.

Solution

Add your ASHX page and make sure you move it to the top of the list.

And in IIS7, you can specify it in web.config:

<system.webServer>
    <defaultDocument>
        <files>
            <clear />
            <add value="my_default_page.ASHX" />
        </files>
    </defaultDocument>
</system.webServer>
