推荐答案
你可以尝试根据用户的远程地址猜测国家.
You can try to guess the country based on the remote address of the user.
以下是一个可行的解决方案，但您必须使用重定向逻辑:
The following is a working solution, you'll have to work the redirection logic though:
$remoteAddr = $_SERVER['REMOTE_ADDR'];
$lookupUrl = sprintf('http://api.hostip.info/country.php?ip=%s', $remoteAddr);
$country = trim(file_get_contents($lookupUrl));
if ('IN' === $country)
{
$newUrl = 'http://www.rajasekar.in/';
header(sprintf('Location: %s', $newUrl));
printf('<a href="%s">Moved.</a>', $newUrl);
exit();
}
不过，请注意来自印度的搜索引擎机器人也能够抓取 .com 内容.
Take care that search engine robots from India are able to crawl the .com content as well however.
