I am using Redis + hhvm
1: When I enable it to replace normal gallery with “justified image gird”(most popular premium gallery) I get this error for all images(none show): ERR_CONTENT_LENGTH_MISMATCH
2: Since mod_pagespeed doesn’t work with redis what alternatives should be used for image compression ? As google pagespeed shows that 90% are unoptimized and gives low score
3: Without w3tc how to setup CDN for images? I tried this: https://rtcamp.com/blog/easyengine-3-3-full-page-redis-cache/ (edited site file) but all it does is take site offline.
