Leverage browser caching

[coliff]

Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.

Currently, most images have a 10 minute cache life.

Can this even be done with GitHub Pages? One would need access to set HTTP headers, which as far as I know, can't be done here.

[coliff]

Good point. Would need to add Cloudflare for this then.

[benmurden]

Can that be done on the free tier? Do you have experience setting that up?

[coliff]

Yes, I've set it up a number of times. It's totally free and has many advantages - including free SSL, so the URL can be: https://hnkansai.org/. I'll post the required steps here shortly....

Quick instructions here. Really easy, setup free Cloudflare account, change Nameservers for the domain to ones provided by Cloudflare.
