How to Fix Default Document in Web.config using IIS 7

A default document is the file that a web server displays when you browse to a folder without specifying a file name.

This is syntax:

<system.webServer>

    <defaultDocument>

      <files>

        <clear />

        <add value="Path of your Page" />

      </files>

    </defaultDocument>

</system.webServer>

Using IIS 7 you can set default document in Web.Config in easy way. Suppose i have to set CommingSoon.aspx page as default page then we should do like this in system.webserver tag.

<configuration>
<system.webServer>
<defaultDocument>
<files>
<add value="CommingSoon.aspx" />
</files>
</defaultDocument>
</system.webServer>
</configuration>

When IIS gets this new default document it adds with parent or global list of default documents.

To remove an individual default document from the list.
<files> 
<remove value="CommingSoon.aspx" /> 
</files>

To remove a default document entry from the inherited or parent list of default documents, do something like this: 

<files> 
<clear/> 
<add value="CommingSoon.aspx" /> 
</files>
