markdown - Fetching referrer URL from a Github-Issue embedded image -


we want place embedded image github issue eg.

https://github.com/org/repo/issues/101

![a cool badge](http://ourserver.io/badge/)

sample badge

on /badge endpoint, our server wants render svg file specific issue special information attached (accepted/rejected/stale/etc), request object doesn't seem contain referrer url, in case https://github.com/org/repo/issues/101 (using node/express), can't distinguish 1 badge on server side without including additional information on query string.

is there way catch referring url before creating badge?

ps: aware of this limitation, though, since not interested in user-browser-specific data, url of issue badge needs rendered to, thought i'd ask.

pps: our current solution generate embed code per issue on our landing page, we'd eliminate step , have universal embed code that's valid on every issue.

all github images proxied https://github.com/atmos/camo security reasons (typically, avoid mixed-content warnings when users paste http urls in https-only github).

github purposefully makes sure image's location (eg. github issue's url) not leak image's origin server (eg. ourserver.io). see following discussion on subject: https://github.com/atmos/camo/issues/43.

the solution put information in image's url: http://ourserver.io/badge/github/org/repo/issues/101.
