Make your website faster with expires headers

Hosting Hangout Recap

This month’s hosting performance hangout on Google+™ focused on using expires headers to speed up your website. Expires headers give context on what Web page info should be served from a cache if it is available. (For example, while a Web page needs to load all its images and related files the very first time a visitor accesses a particular page, subsequent loads usually do not need to reload unchanged images, which takes time.)
