htaccess如果不是子域，请添加www；如果子域不删除www，请添加www [英] htaccess add www if not subdomain, if subdomain remove www

问题描述

我正在尝试做到这一点-可能是最好的例子，所以:

I'm trying to make this - probably example would be the best, so:

domain.com -> www.domain.com
www.domain.com -> www.domain.com
subdomain.domain.com -> subdomain.domain.com
www.subdomain.domain.com -> subdomain.domain.com

因此，如果访问者位于子域中，请不要添加www，并且在设置了www.cn后将其删除.否则，如果不在子域中，请添加www. 我试图写这样的东西，但这不会从子域地址中删除www:/此外，如果可能的话，我不想使用域和TLD域，但要使其尽可能通用. 您能帮我解决问题吗?

So if visitor is in subdomain, don't add www and when is set, remove It. Else if not in subdomain, add www. I tried to write something like this, but this doesn't remove www from subdomain adress :/ Also, if possible, I don't want to use domain and TLD domains but make it as much universal as possible. Could you help me where might be the problem please?

# add www if not subdomain
RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$
RewriteRule ^(.*)$ http://www.%{HTTP_HOST}/$1 [L,R=301]


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

我在根目录中有此文件:

This file I have in root:

# htaccess rules for subdomains and aliases
# to create new subdomain, create a folder www/subdom/(subdomain name)
# to create web for alias, create a folder www/domains/(whole domain name)

# htaccess pravidla pro subdomeny a samostatne weby aliasu
# pro vytvoreni subdomeny vytvorte adresar www/subdom/(nazev subdomeny)
# pro vytvoreni webu pro alias vytvorte adresar www/domains/(cely domenovy nazev)
# dalsi info a priklady: http://kb.wedos.com/r/32/webhosting-htaccess.html

RewriteEngine On

# cele domeny (aliasy)
RewriteCond %{REQUEST_URI} !^domains/
RewriteCond %{REQUEST_URI} !^/domains/
RewriteCond %{HTTP_HOST} ^(www\.)?(.*)$
RewriteCond %{DOCUMENT_ROOT}/domains/%2 -d
RewriteRule (.*) domains/%2/$1 [DPI]

# subdomeny (s nebo bez www na zacatku)
RewriteCond %{REQUEST_URI} !^subdom/
RewriteCond %{REQUEST_URI} !^/subdom/
RewriteCond %{HTTP_HOST} ^(www\.)?(.*)\.([^\.]*)\.([^\.]*)$
RewriteCond %{DOCUMENT_ROOT}/subdom/%2 -d
RewriteRule (.*) subdom/%2/$1 [DPI]

# aliasy - spravne presmerovani pri chybejicim /
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^domains/[^/]+/(.+[^/])$ /$1/ [R]

# subdomeny - spravne presmerovani pri chybejicim /
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^subdom/[^/]+/(.+[^/])$ /$1/ [R]

推荐答案

像这样:

# add www if not subdomain
RewriteCond %{HTTP_HOST} ^[^.]+\.[^.]+$
RewriteRule ^ http://www.%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

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