Can't set the cache headers in GitHub Pages. Now people are criticizing my old portfolio site. Great. Thanks GitHub.

If you're using a custom URL, use Cloudflare for great caching

Ah I would, but I use NameCheap already...

@parion I use Namecheap with Cloudflare all the time! If you go to Cloudflare and put in your URL it'll scan the records, then walk you through how to do it. You'll also get the benefits of a lightning fast JS loader and auto-minify. (On the free plan!)
