i need a script (JavaScript or PHP not mod_rewrite) which can replace all HTTPS to HTTP on all *subdomain.example.com link but keep HTTPS for example.com and www.example.com.
Eg: i want to turn
<a href="HTTPS://sub.example.com">My sub domain</a>
to
<a href="HTTP://sub.example.com">My sub domain</a>
*There will be lot of different sub-domain...

Solution that doesn't require jQuery:
var as = document.getElementsByTagName('a') //get all a tags
var re = /^https:\/\/[\w\W]*(example.com)/i //http://*example.com
var reExcept = /^https:\/\/(www.)?(example.com)/i //filter https://www.example.com and http://example.com
for (var i=0; i<as.length; i++) {
href = as[i].getAttribute('href')
console.log('original href: ' + href)
if (!href || !re.test(href) || reExcept.test(href) )
continue //this href shouldn't be replaced
href = href.replace('https://', 'http://')
as[i].setAttribute('href', href)
console.log('replaced href: ' + as[i].getAttribute('href'))
}
Tested through console at https://www.google.com/search?q=google (with google.com instead of example.com in re and reExept). Seems to work fine.
A bit less wordy version:
var re = /^https:\/\/[\w\W]*(example.com)/i
var reExcept = /^https:\/\/(www.)?(example.com)/i
var as = document.getElementsByTagName('a')
for (var i=0; i<as.length; i++) {
href = as[i].getAttribute('href')
if ( !href || !re.test(href) || reExcept.test(href) )
continue
as[i].setAttribute('href', href.replace(/^https:\/\//i, 'http://'))
}

Here's a solution in PHP. It also covers sub-sub domains like subsub.sub.example.com and domain names only like example.com.
Be aware that when you want to do it on the server side…
So, you can not use a server-side solution for cases where (e.g.) a certificate does not match some subdomain names, while others are matched.
<?php
$tochange = array(
'sub', 'sub1', 'test',
);
$hname = getenv("SERVER_NAME");
if (preg_match('/^(.*)(\.(.*?)\.(.*))$/s', $hname, $regs)) {
// $regs[1] contains subdomain name / names (also: *subsub.sub.domain.tld").
$encrypted = ((isset($_SERVER["HTTPS"])) && (strtoupper($_SERVER["HTTPS"]) == 'ON'));
if ($encrypted && (in_array($regs[1],$tochange))) {
$port = getenv("SERVER_PORT");
$query = ($_SERVER['QUERY_STRING']) ? '?' . $_SERVER['QUERY_STRING'] : '';
$url = 'httpx://' . $hname . $_SERVER['SCRIPT_NAME'] . $query;
// Do a redirect
header("location: $url"); // redirect
// echo "$url<br >"; // for testing
}
}
?>
