What got committed in issue 7401 was only a work-around. There's no way to fully fix this (with sourceCache half gone), but we should at least strive to perform a POST request instead of GET when encountering this case, so we can hope to hit the cache, and send the same data to the server if we miss it (unless we have a chance to stop that second load, I don't know).

I think sourceCache has some code that we can use for this. It should definitely be possible, as evidenced by "View Source".

Issue 7575 has a test case (available for a few more days, at least).

If the response is not in Firefox's cache (e.g. with "Disable Browser Cache" enabled, but Net panel still disabled), a GET is performed. This would be trivial to change but it comforts me to not make automatic double POST requests because non-idempotence etc. The cache ought to be hit in most practical cases I think.

This PHP file works as a test-case: https://gist.github.com/simonlindholm/56331ad07b9854149297

Attaching a test build.

Works fine for me (testing with master). I just get one POST request instead of two requests in 2.0.2.

Works fine for me (firebug-issue7585.xpi). Thanks
