svn: E195019: Redirect cycle detected for URL

In my windows Apache subversion server, I have tried to redirect the request to my local file system. For doing this i added following lines in httpd-custom.conf under 'VisualSVN Server\Bin',  LoadModule alias_module bin/mod_alias.so LoadModule authz_host_module bin/mod_authz_host.so Alias "/svn/MAIN_DB/tags/root/Project3" "D:\root\Project3"   Options FollowSymLinks AllowOverride All Order allow,deny Allow from all   While trying to access(export) the url 'https://mainserver/svn/MAIN_DB/tags/root/Project3' from the svn command line tool, getting the following error,  Redirecting to URL 'https://mainserver/svn/MAIN_DB/tags/root/Project3': Redirecting to URL 'https://mainserver/svn/MAIN_DB/tags/root/Project3': svn: E195019: Redirect cycle detected for URL 'https://mainserver/svn/MAIN_DB/tags/root/Project3'  Is any other configuration is needed?
