The blog is first to be setup at the sub-domain. For ex :In the DNS management of my domain, I used CNAME records to point my sub domain to blogger.
Then I have added a sub directory in my hosting space using c-panel and added 2 files to the folder ( .htaccess and proxy.php)
The htaccess file with below code
RewriteEngine On
RewriteBase /memories
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*)$ proxy.php?url=http://memories.arunraj.eu/$1
The proxy.php file with below code
<?php
$from = "memories.arunraj.eu";
$unto = "arunraj.eu/memories";
function fetch($url) {
$curl = curl_init();
$timeout = 5; // set to zero for no timeout
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
$html = curl_exec($curl);
$content_type = curl_getinfo($curl, CURLINFO_CONTENT_TYPE);
curl_close($curl);
return array($html, $content_type);
}
list($html, $content_type) = fetch($_GET['url']);
// Fix root-relative links etc.
$html = preg_replace('/\b(href|src|rel)="\//', '$1="http://'.$unto.'/', $html);
// Replace the old URL with the new
$html = str_replace($from, $unto, $html);
header("Content-type: $content_type");
echo $html;
?>
Edited the blogger theme in HTML and added the below script under header tags
<script>
if (location.host == memories.arunraj.eu)
{
location.replace(location.href.replace(memories.arunraj.eu, arunraj.eu/memories));
}
</script>
Remember to add the below code in the header if the stylesheet is blocked with error Mixed Content: The page at ‘https://arunraj.eu/memories/’ was loaded over HTTPS, but requested an insecure stylesheet ‘http://arunraj.eu/memories/assets/css/main.css’. This request has been blocked; the content must be served over HTTPS.
<meta http-equiv="Content-Security-Policy" content="upgrade-insecure-requests">
Now accessing the blogger url http://a6unraj.blogspot.com redirects and loads the blog posts in the subdirectory of my domain.
