提供静态内容从一个无Cookie域 - 使用子域名和.htaccess [英] Serving Static Content from a Cookieless Domain - using subdomain and .htaccess
问题描述
我可以有每页许多图像（如70），并希望为他们提供服务，而不cookie的开销。
I can have many images per page (e.g. 70) and want to serve them without the overhead of cookies.
我会preFER设立一个子域，并添加CNAME记录（相对于不必使用一个单独的域）。目前，我有一个CNAME记录我donmain：www.example.com ==> example.com，我想保持解析example.com到www.example.com的功能
I would prefer to set up a subdomain and add a CNAME record (as opposed to having to use a separate domain). Currently, I have a CNAME record for my donmain: www.example.com ==> example.com and I want to keep the functionality of resolving example.com to www.example.com.
我发现，当我使用访问我的网站www.example.com它使用不同的饼干，当我使用example.com的。我可以用的.htaccess重定向到www.example.com要求所有example.com的要求和解决问题的这种方式？将所有Cookie则默认为www.example.com设置什么时候？
I've discovered that when I access my site using www.example.com it uses different cookies from when I use example.com. Could I use .htaccess to redirect all example.com requests to www.example.com requests and solve the problem this way? Would all cookies then default to www.example.com when set?
更新 然后，我会创建CNAME记录static.example.com并将其指向www.example.com。然后，我会指出我所有的图像请求static.example.com。他们会是无Cookie？
UPDATE Then I would create the CNAME record static.example.com and point it to www.example.com. I would then point all my image requests to static.example.com. Would they be cookieless?
推荐答案
是的却是需要的，良好的搜索引擎优化过。多个URL的相同的内容是不是一件好事。您需要进行更改，htaccess文件写在下面。
Yes that's what is needed and good for SEO too. Multiple url for same content is not a good thing. You need to make changes in htaccess file written below.
的RewriteBase /
的RewriteCond％{HTTP_HOST} ^ example.com [NC]
重写规则^（。*）$ http://www.example.com/$1 [L，R = 301]
RewriteBase /
RewriteCond %{HTTP_HOST} ^example.com [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [L,R=301]
