Question

如果我这样做的话:

<IfModule mod_expires.c>
  <FilesMatch ".(ico|pdf|flv|jpg|jpeg|png|gif|swf|mp3|mp4|css|js|php)$">
    ExpiresActive On
    ExpiresDefault "access plus 30 days"
  </FilesMatch>
</IfModule>

It doesn t set properly the Expire header, whereas if I "force" it by hand like this:

<IfModule mod_expires.c>
  <FilesMatch ".(ico|pdf|flv|jpg|jpeg|png|gif|swf|mp3|mp4|css|js|php)$">
    ExpiresActive On
    Header set Expires "Thu, 18 Jan 2012 20:00:00 GMT"
  </FilesMatch>
</IfModule>

It works. This implies 2 things:

mod_expire is installed (IfModule mod_expires.c is true)
the Expire header is not modified after this rule is applied.

我失踪了什么?

顺便说一句:如果你能找到任何解决办法,让我工作!

Ok I ve got it from the official documentation here:

Note that if you use a modification date based setting, the Expires header will not be added to content that does not come from a file on disk. This is due to the fact that there is no modification time for such content.

So it works only for static files, and not for all the other ones: they re not static.

而我也感到迷惑不解,因为AFAIK应该这样工作,我就在考试和测验中尝试过考试,时间不一,时间不一。对我的工作罚款。我的阿帕奇版本

Any the headers for a test file (using chrome developer tools) (with N=15) show:

Date:Mon, 09 Jan 2012 01:48:43 GMT
ETag:"7574-5-4b60e88a820a1"
Expires:Tue, 24 Jan 2012 01:48:43 GMT

我认为,任何<代码>ExpiresDefault均可被否决。 Header set Expires . 否等级等级,以确保<代码>ExpiresDefault在较低级别被压倒。

If you don t want htaccess files doing this you need to disable them in your http config.
