        <rewrite>
            <rules>
                <rule name="Remove index.php" stopProcessing="true">
                    <match url="^(.*)$" ignoreCase="false" />
                    <conditions>
                        <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" />
                        <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" />
                        <add input="{URL}" pattern="^/index\.php/" ignoreCase="false" negate="true" />
