What eat less resources - PHP redirect or .htaccess redirect?

[Guest]

Hello,

currenty, I use PHP to redirect users from http://mydomain.com to http://www.mydomain.com. But using .htaccess seems to be easier (so I don't need to copy the php code to all files). But I am not sure how this affects CPU usage. Do you have any idea what solution is better?

Now, I am using this:

<?php
if (strpos($_SERVER['HTTP_HOST'],"www") === false) {
$url_presmerovat='http://www.'.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
header('HTTP/1.1 301 Moved Permanently');
header('Location: '.$url_presmerovat);
header('Connection: close');
}

?>

...this piece of PHP code is in all files.

I have found 2 .htaccess solutions how to do the same:

Solution 1:

Options +FollowSymLinks
RewriteEngine on
RewriteCond %{HTTP_HOST} ^yoursite.com [NC]
RewriteRule ^(.*)$ http://www.yoursite.com/$1 [L,R=301]

Solution 2:

RewriteEngine On
RewriteCond %{HTTP_HOST} ^yoursite.com
RewriteRule ^(.*)$ http://www.yoursite.com/$1 [R=301,QSA,L]

...I don't understand what does "Options +FollowSymLinks" mean (and I didn't search for it because I don't need to know what does it mean ) but I am really interested to know what is the best solution for lower CPU usage.

Thanks!

I do not know which of these would be more efficient, but using:

Options +FollowSymLinks

in a .htaccess file would result in an error, because the "options" directive has been disabled on our servers.

OK, thanks! I have heard some bad stories about .htaccess in past hours so I decided to use PHP redirect.

I use

RedirectMatch 301 (.*)\.php$ http://www.yoursite.com$1.php
RedirectMatch 301 (.*)\.html$ http://www.yoursite.com$1.html
Redirect 301 / http://www.yoursite.com/

This works fine for me as I have .net and co.uk and redirect them all to .com
So what ever page they are visiting, they are redirected to the correct page on the .com domain.

eg.

https://www.yourdomain.co.uk/signup.php

will get redirected to

https://www.yourdomain.com/signup.php
