Generic htaccess redirect www to non-www

RewriteEngine On
RewriteBase /
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

Same as Michael's except this one works :P

---

But if we need to do this for separate http and https:

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

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

---

Redirect non-www to www (both: http + https)

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

RewriteCond %{HTTPS} on
RewriteCond %{HTTP_HOST} !^www\.(.*)$ [NC]
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R=301,L]

---

If you want to do this in the httpd.conf file, you can do it without mod_rewrite (and apparently it's better for performance).

<VirtualHost *>
  ServerName www.example.com
  Redirect 301 / http://example.com/
</VirtualHost>

I got that answer here: https://serverfault.com/questions/120488/redirect-url-within-apache-virtualhost/120507#120507

Here are the rules to redirect a www URL to no-www:

#########################
# redirect www to no-www
#########################

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

Here are the rules to redirect a no-www URL to www:

#########################
# redirect no-www to www
#########################

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

Note that I used NE flag to prevent apache from escaping the query string. Without this flag, apache will change the requested URL http://www.example.com/?foo%20bar to http://www.example.com/?foo%2250bar

---

RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^/(.*)$ https://%1/$1 [R]

The RewriteCond captures everything in the HTTP_HOST variable after the www. and saves it in %1.

The RewriteRule captures the URL without the leading / and saves it in $1.

---

Try this:

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

If the host starts with www, we stick the whole host onto the start of the URL, then take off the "www."

Complete Generic WWW handler, http/https

I didn't see a complete answer. I use this to handle WWW inclusion.

Generic. Doesn't require domain info. Forces WWW on primary domain: www.domain.com Removes WWW on subdomains: sub.domain.com Preserves HTTP/HTTPS status. Allows individual cookies for domain / sub-domains

Please let me know how this works or if I left a loophole.

RewriteEngine On
RewriteBase /

# Force WWW. when no subdomain in host
RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$ [NC]
RewriteCond %{HTTPS}s ^on(s)|off [NC]
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

# Remove WWW. when subdomain(s) in host     
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteCond %{HTTPS}s ^on(s)|off [NC]
RewriteCond http%1://%{HTTP_HOST} ^(https?://)(www\.)(.+\.)(.+\.)(.+)$ [NC]
RewriteRule ^ %1%3%4%5%{REQUEST_URI} [R=301,L]

There can be a lot of misinformation out there about htaccess redirects, I find. First off, make sure your site is running on Unix using Apache and not on a Windows host if you expect this code to work.

RewriteEngine On

RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]

RewriteRule ^(.*)$ http://%1/$1 [R=301,L] 

(Make sure there are no line spaces between each line of text, though; I have added an extra space between lines so it renders okay in this window.)

This is one snippet of code that can be used to direct the www version of your site to the http:// version. There are other similar codes that can be used, too.

---

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

For subfolder

---

www to non www with https

RewriteEngine on

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

RewriteCond %{HTTPS} !on
RewriteRule (.*) https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

---

For those that need to able to access the entire site WITHOUT the 'www' prefix.

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

Mare sure you add this to the following file

/site/location/.htaccess 

---

Using .htaccess to Redirect to www or non-www:

Simply put the following lines of code into your main, root .htaccess file. In both cases, just change out domain.com to your own hostname.

Redirect to www

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{HTTP_HOST} ^domain\.tld [NC]
  RewriteRule ^(.*)$ http://www.domain.tld/$1 [L,R=301]
</IfModule>

Redirect to non-www

<IfModule mod_rewrite.c>
  RewriteEngine on
  RewriteCond %{HTTP_HOST} ^www\.domain\.tld [NC]
  RewriteRule ^(.*)$ http://domain.tld/$1 [L,R=301]
</IfModule>

I used the above rule to fwd www to no www and it works fine for the homepage, however on the internal pages they are forwarding to /index.php

I found this other rule in my .htaccess file which is causing this but not sure what to do about it. Any suggestions would be great:

############################################
## always send 404 on missing files in these folders

    RewriteCond %{REQUEST_URI} !^/(media|skin|js)/

############################################
## never rewrite for existing files, directories and links

    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-l

############################################
## rewrite everything else to index.php

    RewriteRule .* index.php [L]

---

RewriteEngine on
# if host value starts with "www."
RewriteCond %{HTTP_HOST} ^www\.
# redirect the request to "non-www"
RewriteRule ^ http://example.com%{REQUEST_URI} [NE,L,R]

If you want to remove www on both http and https , use the following :

RewriteEngine on
RewriteCond %{HTTP_HOST} ^www\.
RewriteCond %{HTTPS}s ^on(s)|offs
RewriteRule ^ http%1://example.com%{REQUEST_URI} [NE,L,R]

This redirects Non ssl

http://www.example.com

to

http://example.com

And SSL

https://www.example.com

to

https://example.com

on apache 2.4.* you can accomplish this using a Redirect with if directive,

<if "%{HTTP_HOST} =='www.example.com'">
Redirect / http://example.com/
</if>

---

use: Javascript / jQuery

// similar behavior as an HTTP redirect
window.location.replace("http://www.stackoverflow.com");
// similar behavior as clicking on a link
window.location.href = "http://stackoverflow.com";

Or .htaccess:

RewriteEngine On
RewriteBase /
Rewritecond %{HTTP_HOST} ^www\.yoursite\.com$ [NC]
RewriteRule ^(.*)$ https://yoursite.com/$1 [R=301,L]

and The PHP method:

$protocol = (@$_SERVER["HTTPS"]    == "on") ? "https://" : "http://";

if (substr($_SERVER['HTTP_HOST'], 0, 4) !== 'www.') {
    header('Location: '.$protocol.'www.'.$_SERVER    ['HTTP_HOST'].'/'.$_SERVER['REQUEST_URI']);
    exit;
}

Ajax

$.ajax({
    type: "POST",
    url: reqUrl,
    data: reqBody,
    dataType: "json",
    success: function(data, textStatus) {
        if (data.redirect) {
            // data.redirect contains the string URL to redirect to
            window.location.href = data.redirect;
        }
        else {
            // data.form contains the HTML for the replacement form
            $("#myform").replaceWith(data.form);
        }
    }
});

The only way I got it to work...

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

---

If you are forcing www. in url or forcing ssl prototcol, then try to use possible variations in htaccess file, such as:

RewriteEngine On
RewriteBase /

### Force WWW ###

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

## Force SSL ###

RewriteCond %{SERVER_PORT} 80 
RewriteRule ^(.*)$ https://example.com/$1 [R,L]

## Block  IP's ###
Order Deny,Allow
Deny from 256.251.0.139
Deny from 199.127.0.259

---

This is updated to work on Apache 2.4:

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

The only change vs Michael's is to remove the [NC], which produces the "AH00665" error:

NoCase option for non-regex pattern '-f' is not supported and will be ignored

---

The selected answer and many other solutions here dropped the the part of the url after /, so basically it always redirected to main domain, at least for me.. So i am adding working sample respecting full path after slash..

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

---

Alternative approach if .htaccess customization is not ideal option:

I've created simple redirect server for public use. Just add A or CNAME record:

CNAME   r.simpleredirect.net
A       89.221.218.22

More info: https://simpleredirect.net

---

I am not sure why u want to remove www. But reverse version would be:

# non-www.* -> www.*, if subdomain exist, wont work
RewriteCond %{HTTP_HOST} ^whattimein\.com
RewriteRule ^(.*)$ http://www.whattimein.com/$1 [R=permanent,L]

And advantage of this script is: if u have something like test.whattimein.com or any other (enviroments for developing/testing) it wont redirect U to the original enviroment.

---

Added if localhost, ignore redirection (for development purpose in local environment). If not localhost AND (not https OR it’s www), redirect to https and non-www.

RewriteEngine On

RewriteBase /
RewriteCond %{HTTP_HOST} !localhost [NC]
RewriteCond %{HTTPS} off [OR]
RewriteCond %{HTTP_HOST} ^www\. [NC]
RewriteRule ^(.*)$ https://%{HTTP_HOST}/$1 [R=301,L]

---

Hi you can use following rules on your htaccess file:

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