ruby-on-rails – 为什么在使用Safari和Apache 2.2.3获取Javascr

我们的 Ruby on Rails应用程序的一些用户抱怨说,页面请求偶尔会在Safari下无限期挂起(一对夫妇在Firefox下注意到它,但它绝大多数都是Safari用户).经过一些调查后,我们的Rails应用程序似乎正确地提供了这些请求,并且在获取HTML中引用的图像资源(托管在同一服务器上)时发生挂起.

我们已将Apache配置为直接为图像资源提供服务,并绕过Rails应用程序以提高性能.我们还在text / javascript / css资产上启用了gzip压缩.以下是我们的Apache虚拟主机配置中的相关设置 – 也许我们已经以这样的方式配置了这可以解释这些任意挂起请求？

ExpiresActive On
<FilesMatch ".(ico|gif|jpe?g|png|js|css)$">
  ExpiresDefault "access plus 1 year"
  Header append Cache-Control "public"
</FilesMatch>

以前有没有人遇到过类似的问题？

我们的Ruby on Rails Web应用程序在RedHat Enterprise Linux 5上使用mod_rails和Apache 2.2.3运行.

更新：
我现在尝试删除以下块,问题仍然存在,所以我们可以将expires头排除在问题之外：

ExpiresActive On
<FilesMatch ".(ico|gif|jpe?g|png|js|css)$">
  ExpiresDefault "access plus 1 year"
  Header append Cache-Control "public"
</FilesMatch>

# Safari doesn't handle gzip compression properly; we turn it off by setting 
# the q value to zero for all agents identifying themselves as Safari
RewriteCond %{HTTP_USER_AGENT} Safari
