为什么Facebook泛滥了我的网站? [英] why facebook is flooding my site?

问题描述

每个半小时，我都会收到 http://www.facebook.com的大量请求/externalhit_uatext.php .

Every hour and a half Im getting a flood of requests from http://www.facebook.com/externalhit_uatext.php.

我知道这些要求的含义，但是这种行为很奇怪.

I know what theses requests should mean, but this behavior is very odd.

定期(大约每1.5个小时)，我每分钟会收到许多请求，这些请求是发给我网站上很旧的帖子的-这让我头疼，因为它们没有被缓存...

On a regular basis (aproximatedly every 1,5 hour), Im getting dozen of these requests per minute to very old posts of my site - and this is giving me a headache since they are not cached...

有人知道这可能是什么吗?在什么情况下，Facebook会这样做?

Does anyone know what this could be? In what cases facebook does that?

狮子座，

推荐答案

Facebook Linter将定期访问您的页面以更新OpenGraph数据，这不是您可以控制的，但是您应该考虑以下几点:

Facebook Linter will be visiting your pages periodically to update the OpenGraph data, this isn't something you can control, but there is couple of points you should consider:

• 具有正确且适当的网页缓存/ETag.
• 缓存数据(至少对于匿名用户而言，Facebook bot应该如此).
