I've been diving into web development for about three years now, focusing on WordPress, PHP, JS, CSS, and Python. Recently, I built my own theme and am hosting a few WordPress sites on DigitalOcean with a setup including Debian, CloudPanel, NGINX, Redis, Varnish, and MySQL. Over the past week, I started researching caching and have begun implementing it on my live sites. I'm really impressed with how powerful the cache rules in Cloudflare are, allowing for customization based on factors like queries and cookies.
The more I think about it, the more I realize that caching is crucial for performance, especially when working with PHP and WordPress. I'm shocked at how effective Cloudflare caching is, particularly since it's free and retains freshness for 1-2 days.
Right now, I'm caching my main page and using an Ajax request to check if users are logged in to fetch their data accordingly. My frontend JS adjusts to show or hide elements based on the user's status. I'm trying to strike a good balance between speed and keeping content fresh, so I've opted for a 5-minute browser TTL and a 2-hour edge TTL for my project.
I'd love to know if anyone else has tools or methods for caching to recommend. What do the big players out there typically use?

Honestly, caching is such a big deal! It's like the backbone of web performance. Using something like Cloudflare is just a piece of the caching puzzle—it's not just about having a CDN. It's essential to understand how caching interacts with that CDN to achieve the best performance!
You might want to explore cache warming, which is basically preemptively generating cached versions of your pages. This means that popular pages are ready to go before the user even requests them, ensuring faster load times!
Does this involve just sending requests to those popular URLs? Seems like you'd need tracking to know which pages to prioritize!
For better results, make sure you have some way of tracking performance metrics. This can help in understanding how effective your caching strategy is. We switched to a CloudFront cache for our headless CMS and saw our bandwidth costs decrease significantly—like almost 90%—just from optimizing our caching!
I wouldn’t say caching is underrated. Most experienced developers totally recognize its importance. It's crucial to store frequently accessed content close to users to speed things up.
Exactly! When your browser makes a request and hits the cache, it’s all about serving content directly from Cloudflare, rather than hitting your origin server. Using a CDN like bunny.net for images also helps – it reduces the load there too.
