1235420 - very short Cache-Control headers on video files

Status: RESOLVED FIXED

(Websites Graveyard :: getfirebug.com, defect)

Hi Honza (et al),

We had some trouble with our generic cluster today, and discovered a couple large(-ish) files on getfirebug.com that were sending a max-age=1 header:

https://getfirebug.com/video/Intro2FB.ogv
https://getfirebug.com/video/Intro2FB.mp4

The header is set in the .htaccess file... these MIME types aren't specified, so they get the default of 1s.

These are 13MB each on the filesystem, and during our troubles today the former received around 2200 hits per hour. Many of these were to China, and were (we think) exceptionally slow, and tied up server resources because the files weren't being cached on our load balancers.

At the moment we've implemented a temporary rule on our load balancers to allow these files to be cached, so if you fetch them right now you'll see max-age=3600.

Would you be able to add something like this to your .htaccess file? (exact values copied from your existing settings for images, feel free to tweak)

  ExpiresByType application/ogg "access plus 2592000 seconds"
  ExpiresByType video/mp4 "access plus 2592000 seconds"

Once that's done we'll remove the rule on our end so it can take effect properly.

Thanks!

Done (at revision 149971)

Here is the modified file in the repo:
https://svn.mozilla.org/projects/getfirebug.com/tags/production/.htaccess

It might take some time till it's propagated to the site since the
automated sync is currently broken (see bug 1227926).

Bug 1227926 has been fixed, so this should also work now.
@Jake, can you please verify?
