In one of my project I'm using an external image link to display a screenshot via the GitHub page, which automatically parses the README.rst
I updated this screenshot on my web server several times in the last weeks and I just realised that it is not updated on the GitHub page since... well I think it never updated ;-) GitHub somehow downloaded the image and loads it from it's cache servers.
Within the README.rst, there is clearly the correct link:
Actual link to the ROyWeb screenshot
Which you can confirm, when you load the raw file:
But when I check the URL of the displayed image on the GitHub page, I get:
GitHub cached screenshot of ROyWeb
Does anyone know how to force a "recache"?
