.htaccess 301 redirect subdomain

Hi KbPI,

This should do the trick, if I understand you correctly

RewriteEngine on
RewriteCond %{HTTP_HOST} ^sub.example.com [NC]
RewriteRule /old/ http://sub.example.com/new/ [L,R=301]

Pretty basic redirect - the rule essentially goes like this.. "when requested for /old/, redirect to /new/, but only if HTTP_HOST (the requested host) starts with sub.example.com"

Cheers,
Michael

Hello emptee!

Thank you very much for you help

Cheers!

Edit:

Oops. I have a question, please...

Should I add that code to .htaccess from the "main domain folder" (example.com) or should I create a new .htaccess file inside the sub.example.com folder?

Thank you again

The .htaccess file that needs to be modified.. is whichever one lives in the correct vhost

Eg. if you have two vhosts set up, say...

domain.com -> /home/apache/domain.com/public_html
sub.domain.com -> /home/apache/sub.domain.com/public_html

Then the .htaccess file you'll want to modify would be /home/apache/sub.domain.com/public_html/.htaccess

But.. if you're serving both sub.domain.com and domain.com from the same vhost, then whichever .htaccess file is in the root of that vhost is the right one.

How do you know which configuration you're running if you don't manage the vhosts yourself? Well - simple - if going to either sub.domain.com or domain.com results in the same website being shown, then you most likely only have one vhost configured for both domains.. otherwise.. you've probably got seperate vhosts.

At the end of the day - it doesn't really matter if you put it into the wrong .htaccess file, as it will have no effect at all if it's in the wrong vhost, due to the "but only if HTTP_HOST (the requested host) starts with sub.example.com" condition.

Thank you emptee!

you have been very helpful


Cheers!

Edit:

It's not working

Well, there was a .htaccess file inside sub.domain folder.

Here's what .htaccess looks like before adding that code:

# Use PHP5.4 as default
AddHandler application/x-httpd-php54 .php

# BEGIN WordPress
<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /index.php [L]

</IfModule>

# END WordPress

Does it matters where put the code you gave me? I've tried on almost every line. Top, bottom, middle.

Any ideas, please?
Thank you again

Ahh - you're using wordpress!

I'd just use a plugin if it were me - there are a ton of redirection plugins that will do what you need..

Alternatively, the code would have to go just after the RewriteBase line.. and it may be overwritten if a plugin rewrites your .htaccess file (Yoast does this, from memory...)

Or.. you could put the code at the bottom of the file and make sure /old/ exists within the vhost.

Do yourself a favor and use a plugin - it'll be easier to manage in the future.. and unless you're trying to squeeze the last few visitors out of your server, the performance impact will be negligible.
