We are using CloudFlare for a lot of our projects - some are premium plans, others are free. Recently we found out that outgoing HTTP requests are not proxied through CloudFlare thus revealing the IP address of our server.
This is best demonstrated when a user uploads an image as an avatar that is to be downloaded from our server. When our server requests that image, its origin IP is then recorded in the web server log of the remote server that hosts the image.
How can we prevent that?
Thanks in advance!
