<p><strong>TIL:</strong> <a href="https://til.simonwillison.net/cloudflare/captcha-on-at-least-one-ampersand">Cloudflare CAPTCHA on at least one ampersand</a></p> <p>I'm using Cloudflare's CAPTCHA (they call it a "Web Application Firewall &gt; Custom rules &gt; Managed Challenge" these days) to prevent crawlers from aggresively spidering my <a href="https://simonwillison.net/2017/Oct/5/django-postgresql-faceted-search/">faceted search engine</a> on this site, but I got fed up of even simple <code>?q=term</code> searches triggering the challenge.</p><p>After some mucking around with Claude Code it turns out you can register the following rule instead, so the CAPTCHA only kicks in for search URLs containing at least one ampersand:</p><p><code>(http.request.uri.path wildcard r"/search/*" and http.request.uri.query contains "&amp;")</code></p><p>And now <a href="https://simonwillison.net/search/?q=lemur">/search/?q=lemur</a> works without triggering a CAPTCHA!</p><p>Also included: notes o

<p><strong>Release:</strong> <a href="https://github.com/datasette/datasette-apps/releases/tag/0.1a3">datasette-apps 0.1a3</a></p> <blockquote><ul><li>Fixed a bug where users without the <code>create-app</code> permission could still create apps. <a href="https://github.com/datasette/datasette-apps/issues/27">#27</a></li><li>Fixed a bug where it was impossible to grant permission to edit an app to users who were not the app's owner. The rules for edit/delete are now the same as view: if the app is private only the owner can modify it, otherwise permission is controlled by Datasette's regular permission system. <a href="https://github.com/datasette/datasette-apps/issues/29">#29</a></li></ul></blockquote> <p>Tags: <a href="https://simonwillison.net/tags/datasette">datasette</a></p>
