// This test is to verify Bug 1214079: when we failed to load a signed packaged
// content due to the bad signature, we are able to load in the next time since
// the cache is not cleaned up after signature verification.
//
// In order to verify it, we do two identical requests in a row, where the
// second request will be loaded from cache. The request is made for a signed
// package with bad signature. If the package cache isn't doomed after the
// first load, the second request will get valid data from the cache.
