it was creating issue due to hotspot sheild and ErrorLog, CustomLog; i am using xampp 1.8
<VirtualHost 127.0.0.1:80>
DocumentRoot "C:\xampp\htdocs"
ServerName xampp.local
ServerAlias www.xampp.local
</VirtualHost>
<VirtualHost 127.0.0.1:80>
DocumentRoot "C:\xampp\htdocs\domain\html"
ServerName domain.local.com
ServerAlias www.domain.local.com
after adding it at the end of your httpd-vhosts.conf file restart your xampp and also add following lines to your hosts file available at C:\Windows\System32\Drivers\etc\hosts
127.0.0.1 domain.local.com
127.0.0.1 xampp.local
it will work for xampp 1.8 for remaining xampp versions hope so
