I am trying to figure out how to reduce server load by extending browser caching.
Right now many of the image files only have a cache lifetime of 1 hour, which is almost nothing compared to the standard of 1 year.
This 1 hour is hard-coded into the core because the images come from pluginfile.php/xxxxx/course/overviewfiles/
Is there any way to change this without editing core core?
I have used htaccess to change headers, but found that moodle overrides these headers.
