8 * The sandbox isn't allowed to make XHRs, so they have to be proxied to the
9 * main process. The XMLHttpRequestProxy class is API-compatible with the
10 * XMLHttpRequest class, but forwards the requests to the main process where
11 * they can be serviced. The forwarding of XHRs and responses is handled by
12 * the WcsSandboxContent class; this class is just a thin wrapper to hook XHR
13 * creations by JS running in the sandbox.
15 * Because XMLHttpRequest is implemented natively, and because the intent is
16 * to replace its functionality entirely, prototype linking is not a suitable
17 * approach here, so much of the interface definition is duplicated from the
18 * w3c specification: http://www.w3.org/TR/XMLHttpRequest
