与a2dismod到期,正如预期的那样我没有Expires标题：

随着a2enmod到期,我得到1年的到期回复

我也运行grep来查找任何其他expires语句,但没有.

添加ExpiresByType application / x-javascript后,问题仍然存在.与deflate有冲突吗？

ubuntu@sandBox:/etc/apache2$grep -r application/x-javascript *
mods-available/deflate.conf:        AddOutputFilterByType DEFLATE     application/x-javascript application/javascript application/ecmascript
