// Explanation: the document loaded was loaded from the offline cache. But

// from is different then the manifest the document refers to in the html
// tag. If we detect this during the cache selection algorithm, we must not
// load this document from the offline cache group it was just loaded from.
// Marking the cache entry as foreign in its cache group will prevent
// the document to load from the bad offline cache group. After it is marked,
// we reload the document to take the effect. If we fail to mark the entry
// as foreign, we will end up in the same situation and reload again and
