I recently setup HTTPS (proxy forward using NGINX)
My site shows Secure HTTPS as Mixed Content in chrome when displaying images served by Yahoo weather.
Chrome showed that Yahoo was pulling an image at link below from HTTP source. http://l.yimg.com/a/i/us/we/52/23.gif (this is the image for “windy” weather)
Anyway, I wasn’t sure if this was a big issue but thought it interesting.
only the tab with Yahoo component shows as Mixed Content (HTTP/HTTPS)
All other tabs show HTTPS only (green lock secure)
