. htaccess-如何以通用的方式强制“ www”？

这将把 domain.example改为 www.domain.example:

# Force the "www."
RewriteCond %{HTTP_HOST} !^www\.domain\.example$ [NC]
RewriteRule ^(.*)$ `http://www.domain.example/$1` [R=301,L]

如何替换“域”部分，以便在 任何域工作？

This will do it:

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

The following should prefix 'www' to any request that doesn't have one, and redirect the edited request to the new URI.

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

最佳答案

I would use this rule:

RewriteEngine On
RewriteCond %{HTTP_HOST} !=""
RewriteCond %{HTTP_HOST} !^www\. [NC]
RewriteCond %{HTTPS}s ^on(s)|
RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

The first condition checks whether the %{HTTPS}0 value is not empty (in case of HTTP/1.0); the second checks whether the the %{HTTPS}0 value does not begin with www.; the third checks for HTTPS (%{HTTPS} is either on or off, so %{HTTPS}s is either ons or offs and in case of ons the s is matched). The substitution part of RewriteRule then just merges the information parts to a full URL.

This won't work with subdomains.

domain.example correctly gets redirected to www.domain.example

but

images.domain.example gets redirected to www.images.domain.example

Instead of checking if the subdomain is "not www", check if there are two dots:

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

If you want to redirect all non-www requests to your site to the www version, all you need to do is add the following code to your .htaccess file:

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

RewriteEngine On


RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [NE,L,R=301]

This redirects example.com to www.example.com excluding subdomains.

this worked like magic for me

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

This is an older question, and there are many different ways to do this. The most complete answer, IMHO, is found here: https://gist.github.com/vielhuber/f2c6bdd1ed9024023fe4 . (Pasting and formatting the code here didn't work for me)
