Google Chrome err_failed chrome (err2) - 网络应用
我是一名 Web 应用程序开发人员,运行一个网站 http://myfav.es。我们已经为这个问题苦苦挣扎了大约一个月。
我们使用 HTML 应用程序缓存规范 - www.w3.org/TR/offline-webapps/ - 以及动态生成的清单文件 - myfav.es/personal.manifest - 来加速页面交付。这些动态生成的清单文件使用适当的标头和 PHP 为用户提供自定义清单。
我们还使用 gzip 压缩从 linux/apache 主机为站点提供服务。
在我们网站的生命周期中,用户报告收到类似于 Chrome 中的此屏幕截图的 err_failed 错误。 twitpic.com/272237。
此错误是间歇性的,每 200-300 次访问发生一次,但在每次页面刷新(包括硬刷新)时都会持续存在,这可能意味着使用应用程序缓存的错误导致他们不断加载网站的失败版本。然而,神秘的是,只要清除 cookie 就会导致错误自行修复。
我完全不知道如何处理这个错误,并且谷歌搜索错误消息似乎让大量困惑的用户使用巫术式的方法来解决它。我亲自看到过这个错误,以及其他 Chrome 用户的一些投诉,所以我相当确定它不是由特定用户的设置或浏览器首选项异常引起的。
有谁了解此浏览器错误的原因及其起源?它可能是服务器端还是应用程序设计的副产品?
I'm a web application developer, who runs a site http://myfav.es. We've been struggling with this issue for about a month now.
We use the HTML application cache spec - www.w3.org/TR/offline-webapps/ - with dynamically generated manifest files - myfav.es/personal.manifest - to speed page delivery. These dynamically generated manifest files use proper headers, and PHP to serve up custom manifests for users.
We also use gzip compression to serve the site from a linux/apache host.
For the life-cycle of our site, users report getting a err_failed similar to this screenshot in chrome. twitpic.com/272237.
This error is intermittent, occuring once every 200-300 visits, but will persists on every page refresh, including hard refreshes, which presumably means that an error using app cache is causing them to continuously load a failed version of the site. However, mysteriously JUST clearing cookies causes the error to fix itself.
I'm completely out of ideas on how to approach this error, and googling the error message appears to get a ton of confused users with voodoo-ish approaches to solving it. I've personally seen the error, along with a number of complaint from other users of chrome, so I'm fairly certain it cannot be caused by a particular user having abnormal settings or browser preferences.
Does anyone have any insight into the cause of this browser error and its origins? Whether its likely server-side or a byproduct of app design?
