External images on LinuxFr.org

Our users can use images from external domains on LinuxFr.org. This component is a reverse-proxy / cache for these images.

Th main benefits of using a proxy instead of linking directly the images are:

• No flood: images can be hosted on small servers that are not able to handle all the traffic from LinuxFr.org, so we avoid to flood them
• History: even if a server is taken down, we are able to keep serving images that are already used on our pages
• Security: on the HTTPS pages, we won't include images from other domains that are available only in HTTP, so it prevents browsers from displaying warning about unsafe pages
• Privacy: the users won't connect to the external domains, so their IP addresses won't be logged on these servers.

How to use it?

Install Go and don't forget to set $GOPATH

$ go get -u github.com/linuxfrorg/img-LinuxFr.org
$ img-LinuxFr.org [-a addr] [-r redis] [-l log] [-d dir]

And, to display the help:

$ img-LinuxFr.org -h

Why don't you use camo?

Github has developed a similar service, camo, for their own usage. I used it as a source of inspiration but I prefered to redevelop a new service instead of using it for several reasons:

• It lacks some feature and particulary caching!
• It runs with a legacy version of node.js, which is not very friendly for our sysadmins.
• I plan to extend it for other usages in the future, and I prefer coding in golang than in nodejs.
• And it's a fun component to recode :p
