- kiallmacinnes 13y agoI'm not disagreeing.. but lots of people either dislike relying on JS, or would prefer to have the initial page load be a complete page. If your AJAX is pulling down HTML fragments rather than JSON, then Varnish's ESI gives you the best of both worlds, allowing varnish the gather and assemble the initial page from the same endpoints your JS would hit.
