+/**
+ * Test for Bug 669671.
+ *
+ * This is a bit complicated.  We have a script, file_bug669671.sjs, which counts
+ * how many times it's loaded and returns that count in the body of an HTML
+ * document.  For brevity, call this page X.
+ *
+ * X is sent with Cache-Control: max-age=0 and can't be bfcached (it has an
+ * onunload handler).  Our test does the following in a popup:
+ *
+ * 1) Load X?pushed, to prime the cache.
+ * 2) Navigate to X.
+ * 3) Call pushState and navigate from X to X?pushed.
+ * 4) Navigate to X?navigated.
+ * 5) Go back (to X?pushed).
+ *
+ * We do all this work so we can check that in step 5, we fetch X?pushed from
+ * the network -- we shouldn't use our cached copy, because of the
+ * cache-control header X sends.
+ *
+ * Then we go back and repeat the whole process but call history.replaceState
+ * instead of pushState.  And for good measure, we test once more, this time
+ * modifying only the hash of the URI using replaceState.  In this case, we
+ * *should* load from the cache.
