<rule name="Redirect to WWW" stopProcessing="true" >
<match url="(.*)" />
<conditions>
<add input="{HTTP_HOST}" pattern="^www\." negate="true"/>
</conditions>
<action type="Redirect" url="http://www.{HTTP_HOST}{HTTP_URL}" redirectType="Permanent" appendQueryString="false" />
</rule>
<rule name="SachaFrom" enabled="true" patternSyntax="ECMAScript" stopProcessing="false">
<match url=".*" ignoreCase="true" />
<conditions logicalGrouping="MatchAll" trackAllCaptures="false">
<add input="{URLsToRewriteIn:{REQUEST_URI}}" pattern="(.+)" />
</conditions>
<action type="Rewrite" url="{C:0}" appendQueryString="false" />
</rule>
</rules>
<rewriteMaps>
<rewriteMap name="URLsToRewriteIn">
