Caching the Uncacheable With Varnish<\/h1>\n

[\/et_pb_text][et_pb_text _builder_version=”4.9.0″ text_font=”||||||||” text_text_color=”#666666″ text_font_size=”15px” custom_padding=”0px||||false|false” animation_style=”fade” animation_duration=”1200ms” hover_enabled=”0″ sticky_enabled=”0″]<\/p>\n

When the pressure is on, your application will need to scale up or scale out. Throwing servers at the problem is not a sustainable solution and refactoring is not always effective.<\/p>\n

Caching, on the other hand, might reduce the impact of your application on the system. Unfortunately, when personalization comes into play, caching is really hard: it\u2019s a tradeoff between caching enough variations of your content and maintaining a good hit rate.<\/p>\n

In this presentation, we will use different techniques in Varnish to cache personalized content:<\/p>\n

– Using HTTP fragments such as ESI and AJAX
– Creating cache variations using cookie values
– Authentication on the edge
– Fetching session data on the edge
– Content transformation and personalization on the edge<\/p>\n

By doing as much decision making and transformation \u201con the edge\u201d as possible, we avoid performing expensive computing at the origin, which allows us to scale and to \u201ccache the uncacheable\u201d.<\/p>\n
