Purge GitHubusercontent Camo Cache with this GitHub Action
GitHub badges from services like shields.io are often cached by GitHub using camo. While this caching can improve performance, it can also lead to outdated badge information displayed in your README.md file.

Why Purge Camo Cache?
Before we dive into the specifics of how to use this action, let’s understand why purging the camo cache is important.
GitHub caches external images, including badges from services like codecov and coveritup.app, using githubusercontent camo. This means that instead of loading these images directly from their original sources, GitHub serves them from a proxy server. While this caching improves loading times, it can also cause badge information to become outdated.
Purging the camo cache ensures that the latest data is always displayed on your shield badges. Without cache purging, your badges might show outdated information, which could be misleading to users.
How It Works
This GitHub Action automatically purges the camo cache for images in your README.md file whenever there is a change in the repository. It triggers on push or pull_request events for a branch, ensuring that the cache is refreshed whenever your README.md file is updated.
Additionally, you can use this action with GitHub Actions cron feature to schedule regular cache purging at your preferred intervals.
No Need to Specify Branches or Org Names
One of the highlights of this action is that it automatically detects branch names and organization names, eliminating the need to pass any arguments or configurations. It’s designed to be simple and effortless.
Conclusion
