I have a website that doesn't seem to redirect from non-www to www.
My Apache configuration is as follows:
RewriteEngine On
### re-direct to www
RewriteCond %{http_host} !^www.example.com [nc]
RewriteRule ^(.*)$ http://www.example.com/$1 [r=301,nc]
What am I missing?
This question is related to
apache
redirect
mod-rewrite
The code I use is:
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
<VirtualHost *:80>
DocumentRoot "what/ever/root/to/source"
ServerName www.example.com
<Directory "what/ever/root/to/source">
Options FollowSymLinks MultiViews Includes ExecCGI
AllowOverride All
Order allow,deny
allow from all
<What Ever Rules You Need.>
</Directory>
</VirtualHost>
<VirtualHost *:80>
ServerName example.com
ServerAlias *.example.com
Redirect permanent / http://www.example.com/
</VirtualHost>
This is what happens with the code above. The first virtual host block checks if the request is www.example.com and runs your website in that directory.
Failing which, it comes to the second virtual host section. Here anything other than www.example.com is redirected to www.example.com.
The order here matters. If you add the second virtualhost directive first, it will cause a redirect loop.
This solution will redirect any request to your domain, to www.yourdomain.com.
Cheers!
Do not always use Redirect permanent
(or why it may cause issues in future)
If there is a chance that you will add subdomains later, do not use redirect permanent
.
Because if a client has used a subdomain that wasn't registred as VirtualHost
he may also never reach this subdomain even when it is registred later.
redirect permanent
sends an HTTP 301 Moved Permanently
to the client (browser) and a lot of them cache this response for ever (until cache is cleared [manually]). So using that subdomain will always autoredirect to www.*** without requesting the server again.
see How long do browsers cache HTTP 301s?
So just use Redirect
<VirtualHost *:80>
ServerName example.com
Redirect / http://www.example.com/
</VirtualHost>
<VirtualHost *:80>
ServerAlias example.com
RedirectMatch permanent ^/(.*) http://www.example.com/$1
</VirtualHost>
This is simple!
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
This is similar to many of the other suggestions with a couple enhancements:
%{REQUEST_URI}
rules.The path portion not affected by previous RewriteRule
s like %{REQUEST_URI}
is.
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ %{REQUEST_SCHEME}://www.%{HTTP_HOST}/$1 [R=301,L]
I had a similar task on a WP Multisite, where the redirection rule had to be generic (for any given domain I'd add to the network). I solved first adding a wildcard to the domain (parked domain). Note the . after .com.
CNAME * domain.com.
And then I added the following lines to the .htaccess file at the root of my multisite. I guess it'd work for any site.
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
Hopefully this will help.
ps. If you'd like to redirect from not www to www, change the last line into
RewriteRule ^(.*)$ http://www.%1/$1 [R=301,L]
The following lines can be added either in Apache directives or in .htaccess file:
RewriteEngine on
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ http%{ENV:protossl}://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]
Don't forget to apply the apache changes if you modify the vhost.
(based on the default Drupal7 .htaccess but should work in many cases)
If using the above solution of two <VirtualHost *:80>
blocks with different ServerName
s...
<VirtualHost *:80>
ServerName example.com
Redirect permanent / http://www.example.com/
</VirtualHost>
<VirtualHost *:80>
ServerName www.example.com
</VirtualHost>
... then you must set NameVirtualHost On
as well.
If you don't do this, Apache doesn't allow itself to use the different ServerName
s to distinguish the blocks, so you get this error message:
[warn] _default_ VirtualHost overlap on port 80, the first has precedence
...and either no redirection happens, or you have an infinite redirection loop, depending on which block you put first.
I found it easier (and more usefull) to use ServerAlias when using multiple vhosts.
<VirtualHost x.x.x.x:80>
ServerName www.example.com
ServerAlias example.com
....
</VirtualHost>
This also works with https vhosts.
Try this:
RewriteEngine on
RewriteCond %{HTTP_HOST} ^example.com$ [NC]
RewriteRule ^(.*) http://www.example.com$1 [R=301]
I ran this...
RewriteEngine on
RewriteCond %{HTTP_HOST} !^www.*$ [NC]
RewriteRule ^/.+www\/(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
I need this to be universal for 25+ domains on our new server, so this directive is in my virtual.conf file in a <Directory> tag. (dir is parent to all docroots)
I had to do a bit of a hack on the rewrite rule though, as the full docroot was being carried through on the pattern match, despite what http://httpd.apache.org/docs/2.2/mod/mod_rewrite.html says about it only being stuff after the host and port.
http://example.com/subdir/?lold=13666
=> http://www.example.com/subdir/?lold=13666
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
To 301 redirect all requests made directly to the domain to www you can use:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^([^.]+\.[^.]+){2,}$ [NC]
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
The benefit of this is that this will work if you have any valid subdomains, e.g.
example.com REDIRECTED TO www.example.com
foo.example.com NO REDIRECT
bar.example.com NO REDIRECT
I've just have a same problem. But solved with this
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [R=301,L]
This rule redirecting non-www to www.
And this rule to redirecting www to non-www
RewriteEngine On
RewriteCond %{HTTP_HOST} !^my-domain\.com$ [NC]
RewriteRule ^(.*)$ http://my-domain.com/$1 [R=301,L]
Refer from http://dense13.com/blog/2008/02/27/redirecting-non-www-to-www-with-htaccess/
If you are using Apache 2.4 ,without the need to enable the rewrite apache module you can use something like this:
# non-www to www
<If "%{HTTP_HOST} = 'domain.com'">
Redirect 301 "/" "http://www.domain.com/"
</If>
Redirection code for both non-www => www and opposite www => non-www. No hardcoding domains and schemes in .htaccess file. So origin domain and http/https version will be preserved.
NON-WWW => WWW:
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ %{REQUEST_SCHEME}://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
WWW => NON-WWW:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^ %{REQUEST_SCHEME}://%1%{REQUEST_URI} [R=301,L]
Note: not working on Apache 2.2 where %{REQUEST_SCHEME} is not available. For compatibility with Apache 2.2 use code below or replace %{REQUEST_SCHEME} with fixed http/https.
NON-WWW => WWW:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^ https://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
... or shorter version ...
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTPS}s ^on(s)|offs
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
WWW => NON-WWW:
RewriteEngine On
RewriteCond %{HTTPS} off
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^ http://%1%{REQUEST_URI} [R=301,L]
RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^ https://%1%{REQUEST_URI} [R=301,L]
... shorter version not possible because %N is available only from last RewriteCond ...
This works for me:
RewriteCond %{HTTP_HOST} ^(?!www.domain.com).*$ [NC]
RewriteRule ^(.*)$ http://www.domain.com$1 [R=301,L]
I use the look-ahead pattern (?!www.domain.com)
to exclude the www
subdomain when redirecting all domains to the www
subdomain in order to avoid an infinite redirect loop in Apache.
RewriteEngine On
RewriteCond %{HTTP_HOST} ^yourdomain.com [NC]
RewriteRule ^(.*)$ http://www.yourdomain.com/$1 [L,R=301]
check this perfect work
RewriteCond %{HTTP_HOST} ^!example.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
This starts with the HTTP_HOST
variable, which contains just the domain name portion of the incoming URL (example.com
). Assuming the domain name does not contain a www.
and matches your domain name exactly, then the RewriteRule comes into play. The pattern ^(.*)$
will match everything in the REQUEST_URI
, which is the resource requested in the HTTP request (foo/blah/index.html
). It stores this in a back reference, which is then used to rewrite the URL with the new domain name (one that starts with www
).
[NC]
indicates case-insensitive pattern matching, [R=301]
indicates an external redirect using code 301 (resource moved permanently), and [L]
stops all further rewriting, and redirects immediately.
To remove www
from your URL
website use this code in your .htaccess
file:
RewriteEngine On
RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
RewriteRule ^(.*)$ http://%1$1 [R=301,L]
To force www
in your website URL
use this code on .htaccess
RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^YourSite.com$
RewriteRule ^(.*)$ http://www.yourSite.com/$1 [R=301]
RewriteCond %{REQUEST_fileNAME} !-d
RewriteCond %{REQUEST_fileNAME} !-f
RewriteRule ^(([^/]+/)*[^./]+)$ /$1.html [R=301,L]
Where YourSite.com
must be replaced with your URL
.
<VirtualHost *:80>
ServerAlias example.com
RedirectMatch permanent ^/(.*) http://www.example.com/$1
</VirtualHost>
This will redirect not only the domain name but also the inner
pages.like...
example.com/abcd.html ==> www.example.com/abcd.html
example.com/ab/cd.html?ef=gh ==> www.example.com/ab/cd.html?ef=gh
-If you host multiple domain names (Optional)
-If all those domain names are using https (as they should)
-if you want all those domain names to use www dot domainName
This will avoid doble redirection (http://non www to http://www and then to https://www)
<VirtualHost *:80>
RewriteEngine On
RewriteCond %{HTTP_HOST} ^(?:www\.)?(.+)$ [NC]
RewriteRule ^(.*)$ https://www.%1$1 [R=301,L]
</VirtualHost>
And
<VirtualHost *:443>
RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}$1 [R=301,L]
</VirtualHost>
You should change the redirection code 301 to the most convenient one
