On this page, we can flush any cached pages with force.
The flush job could be an absolute URL like this.
We can specify multiple resources, you can have many separated by newlines.
And alternatively you can flush all resources under a certain URI prefix.
Like /css/ and /js/, all the CSS files and JS files under these two directories will be flushed immediately.
The cache flush jobs are submitted immediately across gateway clusters, so it is not subject to the release process.
