Code Coverage Status Badge is cached

[iSazonov]

Our main ReadMe.md contains Code Coverage Status. The badge looks wrongly due to caching (the badge display old information).

Fix from github/markup#224

We're pretty confident that the image caching works. If you're having issues with something like a CI badge, make sure the image has the Cache-Control: no-cache header, and either Expires , Last-Modified or Etag .

Or workaround from https://github.com/codecov/support/issues/218

[![Coverage](
https://img.shields.io/codecov/c/github/chesslave/chesslave.svg?maxAge=600)]
(https://codecov.io/gh/chesslave/chesslave)

URL param  maxAge  does the trick. The value is expressed in seconds.

@iSazonov The badge seems to showing the latest build. Are you seeing it otherwise?

[iSazonov]

Today I see 33% and on the coveralls.io I see the same.
In recent days I have seen sometimes old up to 4-day badge.

[iSazonov]

Check from another computer - 46% vs 46%. No problem.

@iSazonov So are you OK closing the issue?

[iSazonov]

Yes. We can always come back if the problem appears.

@adityapatwardhan The Issue is up. I see 21% - really 49%.
