Also, hubs should actually notify the hub URL (as part of the discovery links) which means that subscribers will know about the designated hubs with every notification, making it completely optional to have a "routine" polling. It's considered good practice when a feed/publisher changes its hub to have a period during which it *also* pings the old hub (even after the discovery link was removed). </p><p><b>Q:</b> Is it allowed to have the <tt>hub</tt> link in the header, but the <tt>self</tt> link in HTML or vice versa? </p><p><b>A:</b> The spec says: "the publisher SHOULD include at least one Link Header [RFC5988] with rel=hub (a hub link header) as well as exactly one Link Header [RFC5988] with rel=self (the self link header)". That implies that they must be specified together. </p> <h2><span class="mw-headline" id="See_Also">See Also</span></h2> <ul><li><a href="/feeds" class="mw-redirect" title="feeds">feeds</a></li> <li><a href="/streams" class="mw-redirect" title="streams">streams</a></li> <li><a href="/push-vs-pull" title="push-vs-pull">push-vs-pull</a></li> <li><a href="/webmention" class="mw-redirect" title="webmention">webmention</a></li> <li><a href="/webhook" title="webhook">webhook</a></li> <li><a class="external text" href="https://github.com/pubsubhubbub">Prior PubSubHubbub specification</a></li> <li><a href="/Pushl" title="Pushl">Pushl</a></li> <li><a class="external text" href="http://beesbuzz.biz/blog/8139-Some-WebSub-Atom-observations">Some WebSub-Atom observations</a></li> <li><a class="external free" href="https://podnews.net/article/pubsubhubbub-for-podcasters">https://podnews.net/article/pubsubhubbub-for-podcasters</a></li> <li>Silo implementation: YouTube: <a class="external free" href="https://developers.google.com/youtube/v3/guides/push_notifications">https://developers.google.com/youtube/v3/guides/push_notifications</a></li></ul>    </div> <div class="printfooter" data-nosnippet="">Retrieved from "<a dir="ltr" href="https://indieweb.org/wiki/index.php?title=WebSub&oldid=97922">https://indieweb.org/wiki/index.php?title=WebSub&oldid=97922</a>"</div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/Special:Categories" title="Special:Categories">Categories</a>: <ul><li><a href="/Category:building-blocks" title="Category:building-blocks">building-blocks</a></li><li><a href="/Category:jargon" title="Category:jargon">jargon</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" role="contentinfo" > <ul id="footer-info"> <li id="footer-info-lastmod"> This page was last edited on 23 October 2024, at 15:18.</li> <li id="footer-info-copyright">Content is available under <a href="/IndieWebCamp:Copyrights" class="mw-redirect" title="IndieWebCamp:Copyrights">a CC0 public domain dedication</a> unless otherwise noted.</li> </ul> <ul id="footer-places"> <li id="footer-places-privacy"><a href="/IndieWeb:Privacy_policy">Privacy policy</a></li> <li id="footer-places-about"><a href="/IndieWeb:About">About IndieWeb</a></li> <li id="footer-places-disclaimers"><a href="/IndieWeb:General_disclaimer">Code of Conduct</a></li> </ul> <ul id="footer-icons" class="noprint"> <li id="footer-copyrightico"><a href="http://creativecommons.org/publicdomain/zero/1.0/"><img src="https://i.creativecommons.org/p/zero/1.0/88x31.png" alt="a CC0 public domain dedication" width="88" height="31" loading="lazy"></a></li> <li id="footer-poweredbyico"><a href="https://www.mediawiki.org/"><img src="/wiki/resources/assets/poweredby_mediawiki_88x31.png" alt="Powered by MediaWiki" srcset="/wiki/resources/assets/poweredby_mediawiki_132x47.png 1.5x, /wiki/resources/assets/poweredby_mediawiki_176x62.png 2x" width="88" height="31" loading="lazy"></a></li> </ul> </footer> </div> </div> </div> <div class="vector-settings" id="p-dock-bottom"> <ul> <li> <button class="cdx-button cdx-button--icon-only vector-limited-width-toggle" id=""><span class="vector-icon mw-ui-icon-fullScreen mw-ui-icon-wikimedia-fullScreen"></span> <span>Toggle limited content width</span> </button> </li> </ul> </div> <script>(RLQ=window.RLQ||[]).push(function(){mw.config.set({"wgBackendResponseTime":182,"wgPageParseReport":{"limitreport":{"cputime":"0.055","walltime":"0.066","ppvisitednodes":{"value":335,"limit":1000000},"postexpandincludesize":{"value":4272,"limit":2097152},"templateargumentsize":{"value":557,"limit":2097152},"expansiondepth":{"value":4,"limit":100},"expensivefunctioncount":{"value":0,"limit":100},"unstrip-depth":{"value":0,"limit":20},"unstrip-size":{"value":0,"limit":5000000},"timingprofile":["100.00% 29.950 1 -total"," 14.18% 4.248 1 Template:t"," 13.15% 3.939 1 Template:gwg"," 8.93% 2.675 12 Template:sparkline"," 7.37% 2.208 1 Template:barnabywalters"," 7.35% 2.202 1 Template:bret"," 6.79% 2.033 1 Template:mblaney"," 6.57% 1.968 2 Template:aaronpk"," 6.38% 1.912 1 Template:beesbuzz.biz"," 6.21% 1.859 1 Template:main"]},"cachereport":{"timestamp":"20250408062308","ttl":86400,"transientcontent":false}}});});</script> </body> </html>
