检查停放域名的有效方法? [英] efficient way to check parked domains?
问题描述
我正在编写一个脚本来检查给定的域是否已停放.到目前为止,我有这个解决方案:
I am writing a script that checks if given domain is parked or not. so far, I have this solution:
- 在网址末尾添加几个字符.
- 如果 url 重定向到另一个页面并且
- 返回 302 http 状态代码,然后它是停放的域.
- 返回 302 以外的则是正常域.
非常感谢任何建议.
推荐答案
事情并没有那么简单.302 响应仅表示内容暂时位于不同的位置.这可能发生在普通网站上,但并不总是发生在停放的网站上.
It's not as simple as that. A 302 response just means content is temporarily at a different location. This can happen on a normal website and it doesn't always happen on a parked site.
我在一家拥有超过 20,000 个停放域名的 ISP 工作,我们没有在其中任何一个域名上使用 302.
I worked at an ISP with over 20,000 parked domains and we didn't use 302's on any of them.
我认为您不会为此找到 100% 的解决方案.即使您在页面上查看了诸如购买此域名"和此域名可能出售"之类的短语,您也无法确定.
I don't think you'll find a 100% solution for this. Even if you checked the page for phrases such as "Buy This Domain" and "This Domain May Be For Sale" you won't know for sure.
