ETags: a pretty sweet feature of HTTP 1.1

HTTP caching review

HTTP provides two ways for servers to control client-side caching of page components:

• freshness may be based on a date or a token whose meaning is app-specific
• whether or not the client needs to confirm the cached version is up-to-date with the server

This breaks down as follows:

• Cache locally and don't check before using.

<jedp> getting started https://developer.mozilla.org/en-US/docs/Mozilla/Firefox_OS/Preparing_for_your_first_B2G_build
<jedp> slightly out of date, but basically the right steps: https://gist.github.com/jedp/3778932
<jedp> where it says mozilla-inbound, use mozilla-central instead
<jedp> a file called .mozconfig
<jedp> a b2g desktop mozconfig http://www.pastebin.mozilla.org/2752657
<jedp> instead of console.log … used dump("some message\n")
<jedp> to build
<jedp> ./mach build
<jedp> no more make -f client.mk
<jedp> don't do that

B2G Quickstart for Payments and Identity

Before you begin: You want to do this on a Mac. I have been using Linux for months, and unresolved redraw issues (white screen of death) are killing me. Mac works great. Use OSX.

This sets you up to make two separate targets:

• One for a desktop [simulator] [1]
• One for the Unagi [device] [2]

These are the moving parts:

• [mozilla-inbound repo] [3] clone (hg)

# Define where build files should go. This places them in the directory
