I need to create a Sitecore include patch file to add a string to the existing value attribute of the IgnoreUrlPrefixes setting in the web.config.

I have tried to overwriting the default ignored prefixes entirely with the following include file:

<?xml version="1.0"?>
    <configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
        <sitecore>
            <settings>
                <setting name="IgnoreUrlPrefixes">
                    <patch:attribute name="value">/foo/|/sitecore/default.aspx|/trace.axd|/webresource.axd|/sitecore/shell/Controls/Rich Text Editor/Telerik.Web.UI.DialogHandler.aspx|/sitecore/shell/applications/content manager/telerik.web.ui.dialoghandler.aspx|/sitecore/shell/Controls/Rich Text Editor/Telerik.Web.UI.SpellCheckHandler.axd|/Telerik.Web.UI.WebResource.axd|/sitecore/admin/upgrade/|/layouts/testing</patch:attribute>
                </setting>
            </settings>
        </sitecore>
    </configuration>
</settings>

Where /foo/ is the url prefix that I would like to add to the default prefixes. ShowConfig.aspx identifies that the modified configuration has not been applied.

Ideally I would like to be able to simply add /foo/ to whatever exists as the default IgnoreUrlPrefixes values. Does anyone know if this is possible and how to specify it in Sitecore patch syntax?

Good explanation of all possibilities of Sitecore include config files can be found in this John West blog post.

As you can find in the linked post:

patch:attribute: Define or replace the specified attribute.

It does not allow to "add /foo/ to whatever exists as the default IgnoreUrlPrefixes" attribute.
