If you do not wish to use the .htaccess file to redirect your visitors, you can use another option - a PHP or an HTML file which will perform the actual redirection. Below are examples for both programming languages:
For PHP, create a file (index.php for example) and add the following lines in it:
header( 'Location: ' ) ;
For HTML, create a file (index.html for example) with the following content:
CONTENT="0; URL= ">
Here you have the option to delay the redirect by increasing the CONTENT variable. For example CONTENT=5 will delay the redirect for 5 seconds.
