Apache mod 重写重定向
我需要做的：
如果用户访问 test.com 那么服务器必须重定向到 main.com/check.php，检查某些内容并返回到 test。 com
.htaccess:
RewriteCond %{HTTP_HOST} !^main\.com$ [NC]
RewriteRule ^(.*)$ http://main.com/check.php?url=%{HTTP_HOST}%{REQUEST_URI} [L]
check.php
header("location: http://" . $_GET['url']);
但它正在循环。
有什么想法吗？
I need to do:
if user go to test.com then server must redirect to main.com/check.php, checks something and return back to test.com
.htaccess:
RewriteCond %{HTTP_HOST} !^main\.com$ [NC]
RewriteRule ^(.*)$ http://main.com/check.php?url=%{HTTP_HOST}%{REQUEST_URI} [L]
check.php
header("location: http://" . $_GET['url']);
But it`s looping.
Any ideas?

最佳选择 我认为您正在寻找的是：使用公共域跨多个域共享会话。如果是这样，请查看此主题：跨域共享会话
确定选项 如果您不喜欢这样，您可以将所有用户的页面视为单独的服务并实施 单点登录系统。
顽固选项 如果这不是您想要的，并且您想坚持使用 mod_rewrite，我所能建议的就是尝试更多的
RewriteCond来取消循环资格。例如，尝试添加：RewriteCond %{QUERY_STRING} !*some string* [NC, OR]到 @nerkn 建议的顶部（当然，还要在 check.php 中发送查询字符串）。Best Option I think what you're looking for is: Using a common domain to share sessions across multiple domains. If so, check out this SO thread: Sharing sessions across domains
OK Option If you don't like that, you may be able to treat all your users' pages as separate services and implement a Single sign on system.
Stubborn Option If that's not what you're looking for and you want to stick with mod_rewrite, all i could suggest is trying more
RewriteConds to disqualify the loop. For instance, try adding:RewriteCond %{QUERY_STRING} !*some string* [NC, OR]to the top of @nerkn's suggestion (and of course sending a query string in your check.php..htaccess 不知道脚本已检查，所以我添加了引荐来源网址。但这是松散的检查，我认为你应该相信其他机制。如果存在危险的话，推荐人信仰也是危险的。
.htaccess does not know script has checked, so I added referrer. But it is loose check, I think you should believe other mechanism. Referrer belief is dangerous, if there is danger.
