Cloudflare provides a GUI to purge cache, but every action you can perform using the GUI, you can also do with Cloudflare's API. You could use the API to auto purge the cache whenever you update content in your CMS of choice, or purge the cache as part of your Continuous Delivery pipeline. Using PowerShell we'll interact with Cloudflare's API and purge their cache.

Web performance: prevent wasteful hidden image requests (display: none)

- Web
We often hide images using CSS with "display: none", but this doesn't actually prevent the browser from downloading these images. Using the HTML Picture element, we can serve different versions of an image depending on media queries. We can even use a data-img to prevent images from being downloaded at all and optimize our website speed.

Crawling through Umbraco with Robots

- Umbraco
The robots.txt file’s main purpose is to tell robots (Google Bot, Bing Bot, etc.) what to index for their search engine, and also what not to. Usually you want most of your website crawled by Google, such as blog posts, product pages, etc., but most websites will have some pages/sections that shouldn’t be indexed or listed in search engines.
