OK, I think I found a solution:
In Joomla root index.php you should insert this lines written with bold style:
// Set flag that this is a parent file
define( '_VALID_MOS', 1 );
// Redirection for static content as homepage
$host=$_SERVER["REQUEST_URI"];
// check if $_SERVER["REQUEST_URI"] is "/", if yes we go to a special page
if ( $host == "/" ) {
$location="www.yoursite.com/homepage.html";
header( "Location: $location" );
exit();
}
// Enf of redirection for static content as homepage
// checks for configuration file, if none found loads installation page
if (!file_exists( 'configuration.php' ) || filesize( 'configuration.php' ) < 10) {
$self = str_replace( '/index.php','', strtolower( $_SERVER['PHP_SELF'] ) ). '/';
header("Location:
" . $_SERVER['HTTP_HOST'] . $self . "installation/index.php" );
exit();
}
Of course you should change
www.yoursite.com and homepage.html as you want to use!
