 // This file declares a HttpTransactionFactory implementation that can be

 // caching logic follows RFC 2616 (any exceptions are called out in the code).
 //
 // The HttpCache takes a disk_cache::Backend as a parameter, and uses that for
 // the cache storage.
 //
 // See HttpTransactionFactory and HttpTransaction for more details.
