Hi, I've implemented a http discache module for WinCE port's default WinInet backend, and later migrated to cURL.

The impl. is based on Qt's source code, but later trimmed a lot.

The cache file format mainly contains 3 parts: a fixed-size header struct; a http response header, but can be skipped by header-length field of previous struct; the response body.

And it also uses Qt's tricks: such as storing cache file first into a temple file, and later renamed to a url-hashed file name. This may maximize the `ACID` property of low-level file operations.

Hope these information may help you!
