WordPress url error on IIS 7

I have install WordPress as a web applicati开发者_高级运维on at IIS 7 but I have a problem.

When I access the site like http://foo.com/wordpress/ it works great. But when I go to http://foo.com/WordPress/ it give me 404 error. http://foo.com/WordPress/index.php works, but don't give any posts from the database.

So can I do anything that will redirect /WordPress/ or /WORDPRESS/ to /wordpress/?

Its bit older question, but I was dealing with the same issue and haven't found any clear answer, so this might actually help somebody. I fixed the same with following steps:

1) Make sure that the rules in the web.config of the folder with wordpress are case insensitive. My web.config looks like this:

<rewrite>
        <rules>
            <rule name="wordpress" patternSyntax="Wildcard">
                <match url="*" ignoreCase="true" />
                <conditions>
                    <add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
                    <add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
                </conditions>
                <action type="Rewrite" url="index.php" />
            </rule>
        </rules>
    </rewrite>

2)Install and activate WordPress plugin (the first code snippet) from this link: case insensitive permalinks

It isn't the best solution, because it doesn't make the nice canonical url's with 301 permanent redirect for example, but works as a quick fix.
