Question

I know that, wordpress redirects closely matched urls to its original url.However, I need to know the actual url at the very beginning of code execution. Is it possible?

1) If there is any method that takes a url as parameter and returns its original wordpress url
, that would be great, but not sure, whether it exists or not. Is there something like that?

2) where in the code actually does this test and redirection please?

3) Is there any hook that I can use to add a plugin to control this situation?

Thanks in advance.

Example:

Suppose, I have a post on this url: “http://mydomain.com/example-post-page”

Now if I try to access it via “http://mydomain.com/example-post-page/”, it will redirect you to original first url. It is true for other several small changes in url, all will redirect you to the actual permalink url.

My goal is to control this redirection. That’s why, when I am on “http://mydomain.com/example-post-page/” , I like to know(my code in on root index.php) whether this is the origianl permalink or is that something else, before it redirects.

Ok, At last I got it done in the following way and seems ok for me:

1) Recieve approx url.
2) Make a cURL request using this approx url.
3) get response url.
4) return the response url.

Code given below:

function get_actual_url($approx_url){
$curlObj = curl_init();
curl_setopt($curlObj, CURLOPT_URL, $approx_url);
curl_setopt($curlObj, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curlObj, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($curlObj, CURLOPT_ENCODING , "gzip");
curl_setopt($curlObj, CURLOPT_TIMEOUT,180);

$content = curl_exec($curlObj);

$info = curl_getinfo($curlObj);
curl_close($curlObj);

if(!empty($info) && !empty($info["url"])){
    return $info["url"];
}
else {
    return $approx_url;
}}
