Hi Melih,

Edit your umbracoSettings.config in the Config folder.

Change your requestHandler tag

  <requestHandler>
<!-- this will ensure that urls are unique when running with multiple root nodes -->
<useDomainPrefixes>true</useDomainPrefixes>
<!-- this will add a trailing slash (/) to urls when in directory url mode -->
<addTrailingSlash>true</addTrailingSlash>   
   <urlReplacing removeDoubleDashes="false" toAscii="false">
