First Byte Time and Specify a cache validator

[pmeenan]

Well, right there, your last 2 rules:

Code:

<ifModule mod_headers.c>
Header unset ETag
</ifModule>
FileETag None
<ifModule mod_headers.c>
Header unset Last-Modified
</ifModule>

You are explicitly removing the Last-Modified and ETag headers. At a minimum you should remove the last rule that removes the Last-Modified header. ETag is up to you (doesn't really add much value but it won't hurt in your config either).

This could also be a problem:

Code:

<filesMatch "\\.(js)$">
Header set Cache-Control "max-age=2160000, private"
</filesMatch>

It is telling intermediate proxies (like MaxCDN) to not cache the content. Change the private to public and see if it gets better.
