Question

我在几周前改变我的服务器的目录结构后,从面板上抽出403和404个错误。当然,在这种局面中,这种错误应当预料到,直到ache清为止,而且在大多数情况下都是如此。然而,对于一组选定的股份链接,我仍然发现这一错误。我一再试图通过相应网页的“ de”工具清除海滩,一切都看着产出是完美的,但坏要求不断提出。 (Lint tool: lint tool url。) 我的记录中有一些例子:

HTTP 查阅记录:

69.171.224.251 - - 443 [13/Jan/2012:06:22:01 -0500] "GET /web/user/images/b0/b0ahhSjq1C1oEX0TBS5gLAmcSX4wKdPT.240.jpg HTTP/1.1" 403 338

[Fri Jan 13 05:55:01 2012] [error] [client 69.171.228.249] File does not exist: /var/xxx/www/html/web/user/images/1/ab/abSIktLHDs3rcUPYyFtxsP8J9u7vvaVr.240.jpg

这些IP地址是背书。

也许,我对错误的ur弄? 我如何发现这些要求属于什么? t是否在一段时期后停止要求,并恢复其切身? 上周的第二次错误是每天25次。

(At this point I would not consider url rewriting.)

你们应当设立301个永久方向。或者做某种ur。这两种方式都是行之有效的。

Facebook needs to scrape your page to know how to display it around the site.

Facebook scrapes your page every 24 hours to ensure the properties are up to date. The page is also scraped when an admin for the Open Graph page clicks the Like button and when the URL is entered into the Facebook URL Linter. Facebook observes cache headers on your URLs - it will look at "Expires" and "Cache-Control" in order of preference. However, even if you specify a longer time, Facebook will scrape your page every 24 hours.

The user agent of the scraper is: "facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)"
