While working on some optimizations for my site, I noticed some things in Networking Timings for Chrome Developer Tools differ from those in Firefox Developer Tools.Very consistently Chrome loads a number of items on the page giving a 200 (from cache) response. Those same items on Firefox just show as 304 response items.I am wondering if anyone can explain this. Below are two screen shots for the same resource. First one from Chrome, the second from Firefox.
When using resources from cache Firefox show a 304 response but Chrome says 220 (from cache)
