BTW CloudFlare got a free plan, and it’s easy to set up so that it doesn’t interfere:
- Add a cdn subdomain to your hosting;
- Add your domain to CloudFlare;
- On CloudFlare, disable CDN for all subdomains except for cdn.
- Set up your site to serve static content from cdn.*. Do it by hand, by
mod_rewriteor whatever — I am using WordPress “WP Super Cache” plugin here.
