.htaccess redirection - two sharing websites - apache

I have two websites that is actually the same where example.com shares all files from examples.com. So whatever changes made in exampples.com, example.com automatically gets updated. That means they have the same .htaccess file.
The problem is, I want to both sites redirects to non www to a www url. I got this:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]


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


This should do it:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example\.com$ [NC,OR]
RewriteCond %{HTTP_HOST} ^examples\.com$ [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
Basically you're adding an OR condition to say if either example.com or examples.com doesn't begin with www. then add it to the respective domain name.


replace example.com with %{HTTP_HOST} to make your rules host independent

rewrite www. to without www. in .htaccess for hostname instead of writing in the website name?

I currently use:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^www.e-innovate.co.uk [NC]
RewriteRule ^(.*)$ http://e-innovate.co.uk/$1 [L,R=301,NC]
But what i am trying to do is create a general rewrite code which i can drop into .htaccess files without having to change the domain name such as below, i dont seem to be able to get this to work, am i on the right track ?
Thanks
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://%{HTTP_HOST}/$1 [R=301,L]

Try:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
note that this will also get applied to subdomains.

Redirecting Subdomain to WWW using .htaccess

I'm trying to redirect a specific subdomain to www. I already have rules in place that will redirect non-www to www.domain.com. Here is what I currently have, and it works fine:
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^([^.]+\.[a-z]{2,6})$ [NC]
RewriteRule ^(.*)$ http://www.%1/$1 [R=301,L]
My problem is that some requests are coming in for ns2.domain.com, and I would like those redirected to www.domain.com as well. Any help?

Try adding an extra [^.]+\. in your second condition:
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^[^.]+\.([^.]+\.[a-z]{2,6})$ [NC]
RewriteRule ^(.*)$ http://www.%1/$1 [R=301,L]

Properly redirecting a subdomain to subdirectory invisibly

I know similar things have been asked before, but none of the solutions I've found have seemed to work out. I'm by far an expert when it comes to mod_rewrite and it's ilk, so apologies if I'm missing something obvious.
I am trying to invisibly redirect subdomains to an index.php file in a subdirectory; this file takes the value of the subdomain as part of the query string, which is working fine.
The problem I'm having is that now everything in this subdirectory is being redirected to the index.php file, which I don't want to happen.
This is what I have thus far:
RewriteEngine On
RewriteBase /
# User dashboards
RewriteCond %{HTTP_HOST} ^(.*)\.example\.com [NC]
RewriteRule ^.*$ app/index.php?user=%1 [L,NC,QSA]
What I'm looking for is a situation where http://subdomain.example.com/ will lead to /app/index.php?user=subdomain, but http://subdomain.example.com/assets/stylesheet.css will go to /app/assets/stylesheet.css.
Thanks in advance!

If i understood well your example, you can do it this way:
redirects example.com to www.example.com to avoid having "empty" subdomain
internally rewrites every root subdomains (except www) to /app/index.php?user=subdomain
internally rewrites other things with "app" prefix
Which is represented by this code
RewriteEngine on
# redirects example.com to www.example.com to avoid having "empty" subdomain
RewriteCond %{HTTP_HOST} ^example.com$
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
# internally rewrites every root subdomains (except www) to /app/index.php?user=subdomain
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTP_HOST} ^([^.]+)\. [NC]
RewriteRule ^/?$ /app/index.php?user=%1 [L,NC,QSA]
# internally rewrites other things with "app" prefix
RewriteCond %{THE_REQUEST} !app/
RewriteRule ^/?(.+)$ /app/$1 [L,NC,QSA]
EDIT: as you asked in below comments, here is how to manage also www subdomain
RewriteEngine on
# redirects example.com to www.example.com to avoid having "empty" subdomain
RewriteCond %{HTTP_HOST} ^example.com$
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
# internally redirects www subdomain root to /site/index.php
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteRule ^/?$ /site/index.php [L]
# internally rewrites every other root subdomains to /app/index.php?user=subdomain
RewriteCond %{HTTP_HOST} ^([^.]+)\. [NC]
RewriteRule ^/?$ /app/index.php?user=%1 [L,NC,QSA]
# internally rewrites other things with "app" prefix
RewriteCond %{THE_REQUEST} !app/
RewriteRule ^/?(.+)$ /app/$1 [L,NC,QSA]

Let add second rule to redirect assets to app/assets:
RewriteCond %{HTTP_HOST} ^(.*)\.example\.com [NC]
RewriteCond %{REQUEST_URI} !\.(css|js|png|jpg|gif)$ [NC]
RewriteRule ^.*$ app/index.php?user=%1 [L,QSA]
RewriteRule ^assets/(.*)$ app/assets/$1 [L,QSA]
or load all css/js/images directly from app:
RewriteCond %{HTTP_HOST} ^(.*)\.example\.com [NC]
RewriteRule ^.*\.(css|js|png|jpg|gif)$ app/$0 [NC, QSA]
RewriteRule ^.*$ app/index.php?user=%1 [L,QSA]
EDIT: Sorry, I haven't tested it before, so there is working example:
RewriteRule ^assets/(.*)$ app/assets/$1 [L,QSA]
RewriteCond %{HTTP_HOST} ^(.*)\.example\.com [NC]
RewriteRule !^app/assets/ app/index.php?user=%1 [L,QSA]

Apache: redirect if host doesn't start with www or cdn

My goal is to redirect to domain with www. if both these conditions are met:
current host is not www.example.com
current host is not cdn.example.com
I'm using a .htaccess file with this code, but the second condition is not honoured:
RewriteCond %{HTTP_HOST} !^www\.example\.com [NC]
RewriteCond %{HTTP_HOST} !^cdn\.example\.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
Thank you

Using this did the trick:
RewriteCond %{HTTP_HOST} !^(cdn|www)\.example\.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
I already tried it before but was tricked --by a cached redirect-- to think it was not working.

htaccess: exluce some domain in RewriteCond

this is my .htaccess code
so if the user type just domain.com will be redirected to www.domain.com
RewriteBase /
RewriteCond %{HTTP_HOST} !^www.domain.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com/$1 [L,R=301]
my problem now is that i have a new domain pointing to the same domain path
so even the new domain is redirected "transparently" to domain.com...
how can i exclude some domain name from that rule?
thanks!

You could try making the rewrite generic, so all requests that are not starting with www are redirected, but on the correct/requested domain.
RewriteCond %{HTTP_HOST} !^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://www.%1/$1 [L,R=301]
Or, you can check instead for if the domain starts with domain.com:
RewriteCond %{HTTP_HOST} ^domain\.com$ [NC]
RewriteRule ^(.*)$ http://www.domain.com [L,R=301]
Hopefully this helps.
