Apache redirect from one subdomain to another - apache

Does anyone know a way to do a permanent redirect from a.example.com to b.example.com? I have other subdomains that need to remain as they are though. so:
first.example.com -> second.example.com
third.example.com is fine
fourth.example.com is fine
I want to do this in the <VirtualHost> block rather than an .htaccess to avoid having to redeploy again.
Any thoughts would be appreciated, thanks

Add the following RewriteRule to your VirtualHost
RewriteEngine On
RewriteCond %{HTTP_HOST} ^first.example.com$
RewriteRule ^ http://second.example.com [R=301,L]
If you wanted to redirect first.example.com/some/url to second.example.com/some/url:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^first.example.com$
RewriteRule /(.*) http://second.example.com/$1 [R=301,L]
Recommend you use [R=302] whilst testing the rules to avoid problems with 301s getting cached by your browser.

Apache 2.2 - "Split" domain

I'm very new to Apache and already run into an problem which already takes a lot of time and I'm not even sure if it's possible.
I have two servers and one Domain called szop.in which is having an A record to my first server. On the first server I'm running an URL shortener called YOURLS, it's under szop.in/admin. I want the second server serve my homepage, therefor I want to redirect all requests like szop.in or http://subdomain.szop.in to the second server but not http://szop.in/admin.
Is this possible?
This doesn't seem to be the right solution and the mod_rewrite is causing me some headache:
RewriteEngine On
RewriteCond %{HTTP_HOST} szop.in [NC]
RewriteRule !^/admin$ hxxp://other-domain.in [R=301,L]
My idea was, since I need just one URL to work on the first server http://szop.in/admin, to redirect everything that is not starting with /admin to the other domain.
You almost got it:
Options +FollowSymLinks -MultiViews
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^szop\.in$ [NC]
RewriteCond %{REQUEST_URI} !^/admin [NC]
RewriteRule ^ http://subdomain.szop.in%{REQUEST_URI} [R=301,L]
You cannot use the negation on the RewriteRule like that, you use it on a conditions.
This should do what you want, it verify if domain is szop.in and if folder is not /admin and redirect to subdomain.szop.in.

Mod Rewrite, Unexpected Results

We are trying to redirect everything from one domain to another with the following
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.example\.com$ [NC]
RewriteRule .? http://www.example2.com%{REQUEST_URI} [R=301,L]
When we visit http://www.example.com/v2sc
We are being redirected to http://www.example2.comv2sc
We would like to be redirected to http://www.example2.com/v2sc considering www.example2.comv2sc is not a valid hostname
Any ideas on how we can accomplish this?
Thank you!
It seems like you're using a .htaccess file for this. In that context the leading slash is not present in %{REQUEST_URI} so it's up to you to put it back in.
RewriteEngine On
RewriteCond %{HTTP_HOST} !=www.example.com
RewriteRule ^ http://www.example2.com/%{REQUEST_URI} [R=301]
Please also note that solutions like this should be used only if you cannot edit the main server configuration file. Doing so would allow you to use a cleaner combination of vhosts and Redirect directives that would run much more quickly.

URL Rewriting using .htaccess

To change the URL /mobiles.php?id=5 to /mobiles/5
The content of .htaccess file is as follows:
Options +FollowSymlinks
RewriteEngine on
RewriteRule /mobiles/$1 ^/mobiles.php?id=([0-9]+)$
But still it is showing /mobiles.php?id=5 in the address bar. Please help. Is there anything else needs to be added in the .htaccess file?
Note:
mod_rewrite module is enabled
I have restarted Apache server after making changes to the .htaccess
file
.htaccess file is in htdocs folder of Apache.
I am using Windows + PHP + Apache + MySQL
This works for me:
Options +FollowSymlinks
RewriteEngine On
RewriteBase /
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^mobiles/([0-9]+)$ mobiles.php?id=$1&rew [L]
RewriteCond %{QUERY_STRING} ^id=([0-9]+)$
RewriteRule ^mobiles.php$ /mobiles/%1? [R,L]
If you see this line:
RewriteRule ^mobiles/([0-9]+)$ mobiles.php?id=$1&rew [L]
I have added rew variable in the query string to prevent Apache to fall in an infinite loop
When Apache execute this line:
RewriteCond %{QUERY_STRING} ^id=([0-9]+)$
Is to make sure that url has not been rewritten for Apache
If your only concern is that the old url stays in the address bar, and you want this not to happen, try adding an [R] at the end.
RewriteRule ^/mobiles.php?id=([0-9]+)$ /mobiles/$1 [R]
Did you actually see the correct page?
By the way, the rewrite rules generally go the other way. I would be expecting to see something like:
RewriteRule ^/mobiles/([0-9]+)$ /mobiles.php?id=$1
Is your concern one of making sure a URL with query parameters does not show up in the address bar?
If I understand correctly, you want
Internally redirect /mobiles/5 to /mobiles.php?id=5
Also redirect the browser TO /mobiles/5 if a user navigates to /mobiles.php?id=5
For this you need 2 rules one to internally rewrite the URL for 1st case and 2nd for browser redirection.
You can do it like this:
RewriteEngine on
# for internal rewrite
RewriteRule ^/?mobiles/([0-9]+)/?$ /mobiles.php?id=$1 [L]
# for browser redirect
RewriteRule ^/?mobiles\.php\?id=([0-9]+)$ /mobiles/$1/ [R,L]
You are doing the opposite, should be:
RewriteRule ^/something/mobiles/([0-9]+)$ /something/mobiles.php?id=$1

Apache mod_rewrite: can these simple RewriteRule be improved? And suggestions!

I started finally to understand Apache mod_rewrite. It's pretty GREAT!
Plz have a look at the followings:
1) Permanent redirects http://www.domain.com/folder_name/ (with or without final slash and with or without the www) to http://www.domain.com/some/path/some_page.html
RewriteRule ^folder_name[/]*$ "http\:\/\/domain\.com\/some\/path\/some_page.html" [R=301,L]
2) Permanent redirects all requests to www.domain.com... to same path and file request but without www in domain
RewriteCond %{HTTP_HOST} !^domain.com$
RewriteRule ^(.*)$ "http\:\/\/domain\.com\/$1" [R=301,L]
They all work as expected and do their jobs, I'm simply curios if some guy, who is more expert than me in mod_rewrite, could give me some advises like: "it could be better in this way...", "there might be a problem if...", etc.
Thanks!
Use the ? quantifier instead of * and you don’t need to escape the substitution URL:
RewriteRule ^folder_name/?$ http://example.com/some/path/some_page.html [R=301,L]
You might want to consider HTTP 1.0 requests where the Host header field is missing. Another useful extension would be to take HTTPS into account:
RewriteCond %{HTTP_HOST} !^(|example\.com)$
RewriteCond %{HTTPS} ^on(s)|
RewriteRule ^ http%1://example.com%{REQUEST_URI} [R=301,L]

301 redirect .htaccess

Im trying to request the following entire site 301 redirect:
word.something.blah.domain.com --> http://www.word.com
I don't know how to write the 301 redirect rule.
Can someone help out?
I will assume you are using the same directory to serve files on both domains. In which case, a Redirect clause won't work (infinite redirect loop).
With mod_rewrite, you can check the value of the current HTTP_HOST and take a decision based on that:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^([a-zA-Z0-9]+)\.something\.blah\.domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.%1.com/$1 [R=301,NE,L]
put this into root directory of the subdomain:
Redirect permanent / http://www.word.com
If you are keeping everything else the same - that is, the file names - but simply changing the domain, this code is all you need to put on the OLD DOMAIN htaccess:
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www\.newdomain\.co.uk
RewriteRule (.*) http://www.newdomain.co.uk/$1 [R=301,L]
