ExpiresByType "access plus 1 month" results in 1 year expires header

Question

I have implemented resourec expiry with the following set up

<IfModule mod_expires.c>
    ExpiresActive On
    ExpiresByType image/jpg "access plus 1 year"
    ExpiresByType image/jpeg "access plus 1 year"
    ExpiresByType image/gif "access plus 1 year"
    ExpiresByType image/png "access plus 1 year"
    ExpiresByType text/css "access plus 1 month"
    ExpiresByType application/pdf "access plus 1 month"
    ExpiresByType application/x-javascript "access plus 1 month"
    ExpiresByType text/javascript "access plus 1 month"
    ExpiresByType application/x-shockwave-flash "access plus 1 month"
    ExpiresByType image/x-icon "access plus 1 year"
    ExpiresDefault "access plus 2 days"
</IfModule>

with a2dismod expires, as expected I have no Expires header:

    wget --server-response --no-check-certificate https://sandbox.trinityp3.com/wp-includes/js/jquery/jquery.js?ver=1.12.4

with a2enmod expires however I do get a 1 year expires response

  wget --server-response --no-check-certificate https://sandbox.trinityp3.com/wp-includes/js/jquery/jquery.js?ver=1.12.4

I have also run grep to find any other expires statements, but there are none.

After adding ExpiresByType application/x-javascript the problem still persists. Could there be a conflict with deflate?

ubuntu@sandbox:/etc/apache2$ grep -r application/x-javascript *
mods-available/deflate.conf:        AddOutputFilterByType DEFLATE     application/x-javascript application/javascript application/ecmascript
sites-available/710-tp3-au-www-sandbox.conf:    ExpiresByType     application/x-javascript "access plus 1 month"
sites-available/710-tp3-au-www-sandbox.conf:    ExpiresByType     application/x-javascript "access plus 1 month"

Try changing "ExpiresByType image/jpg "access plus 1 year" (and so on) by "ExpiresByType image/jpg "access plus 2 year" and see if you get 2 years response? — bgtvfr, Oct 19 '18 at 09:44
@bgtvfr suggestion is a starting point; I would change *all* the "plus one year", so that you do not have any "plus one year" at all in your config file. Make them all different (3 days, 4 days, 5 days, etc.) If you get one of them you'll know which one it is. If you continue getting one year, it can be because you have not restarted (or maybe not the right process), because the file is not the right file, or maybe because it is being overridden (maybe your grep did not find the overriding file). — Law29, Oct 21 '18 at 10:03
Thanks @law29. I have changed them and also removed the surrounding — jdog, Oct 23 '18 at 03:23
Since you have the wget command to check, I suggest you check from localhost so you don't go through the ELB. — Law29, Oct 23 '18 at 14:34

You have no ExpiresByType rule for the application/x-javascript Content-Type your .js file is being served as.

It seems obvious, but doesn't solve the problem. I have updated the question – jdog Oct 16 '18 at 21:08
@jdog Did you restart apache? What is your current configuration? – Michael Hampton Oct 16 '18 at 21:55
Yes I did, have also re-pasted config lines from apache vhost just now – jdog Oct 16 '18 at 22:45
