Something like this should support Pubsubhubbub and rss-cloud. After having implemented something like this[0], I based my own feedreader[1] completely on superfeedr[2], which supports those push notifications as well and crawls the feeds in very small intervalls if not. That get rids of the problem of having to refresh the feeds completely.<p>[0]: <a href="https:&#x2F;&#x2F;github.com&#x2F;onli&#x2F;rsspusher" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;onli&#x2F;rsspusher</a>, now defunct<p>[1]: <a href="https:&#x2F;&#x2F;onli.github.io&#x2F;feedtragon&#x2F;" rel="nofollow">https:&#x2F;&#x2F;onli.github.io&#x2F;feedtragon&#x2F;</a><p>[2]: <a href="https:&#x2F;&#x2F;superfeedr.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;superfeedr.com&#x2F;</a>
