Thank you very much rexkogitans.
I really appreciate your feedback/info.
Hello, Norbert,
first of all I want to introduce my situation a bit. I am IT
sysadmin at a telecommunication who is responsible for setting up
web servers. We also have the situation that customers load a site
or a part of a site, say the CSS files or JQuery, a hundred times
an hour whice is really not necessary.
In the view of HTTP, caching is always an advice that is given
from the server to the client. It is the client's responsibility
(i.e. its specific behaviour to follow this advice) to really
cache the files and not re-request them from the server.
In HTTP 1.1, the caching is a simple HTTP header field, see
section 14.9 here:
https://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html
So, for example:
Cache-Control: max-age=3600, public
to advice the client a cache of 3600 seconds. You may want to
adjust the value to your needs.
Since you do not want every file to be cached, you may want to
put the header under a condition:
<FilesMatch "\.mp4$">
Header set Cache-Control "max-age=3600, public"
</FilesMatch>
You can put this into the virtual host configuration file or into
the .htaccess file.The FilesMatch directive is described here:
https://httpd.apache.org/docs/2.4/de/mod/core.html#filesmatch
and the string "\.mp4$" is a Regular _expression_ to match the file
names.
Kind regards,
rexkogitans

Anyone know a company that I can pay to get solid advice on
this?
I mean a company that actually knows what to do in my
situation, instead of just accepting my money and then using
Google/Stack Overflow to see what information they can give me.
Best regards,
Norbert

Hi folks,
When I'm serving up many (huge) MP4 files via HTML5 <video>, and want
heavy caching to keep traffic down, is the following suitable
public_html/.htaccess content?
=====
<IfModule mod_expires.c>
<FilesMatch "\.(mp4)$">
ExpiresActive On
Header set Expires "Mon, 27 Mar 2038 13:33:37 GMT"
</FilesMatch>
</IfModule>
=====
Thanks!
Best regards,
Norbert
