完整的通用WWW处理程序，http/https

我没有看到一个完整的答案。我用这个来处理WWW的包含。

通用的。不需要域信息。 强制WWW主域:www.domain.com 删除子域名sub.domain.com上的WWW 保持HTTP/HTTPS状态。 允许域/子域单独的cookie

请让我知道这是如何工作的，或者如果我留下了漏洞。

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]

重定向非www到www(均: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]

如果.htaccess定制不是理想的选择:

我创建了简单的重定向服务器供公众使用。只需添加A或CNAME记录:

CNAME   r.simpleredirect.net
A       89.221.218.22

更多信息:https://simpleredirect.net

但是如果我们需要为单独的http和https这样做:

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]

使用: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";

或. htaccess:

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

PHP方法:

$protocol = (@$_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);
        }
    }
});

更新后可以在Apache 2.4上工作:

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

与Michael的唯一变化是删除[NC]，这会产生“AH00665”错误:

不支持非正则表达式模式“-f”的NoCase选项，将被忽略
