Ask HN: Is there a wget alternative which can download https files from a cache?

Now many tools/libs/framework (docker, chef, vagrant etc) downloads files from s3 on the fly. The download link's schema is the awesome "https". But a normal proxy can't cache the https downloads, any idea on how to tackle it?

E.g, When using vagrant and chef, each vm will run some cookbooks, and it is quite normal that a cookbook triggers a wget download in each vm. And when you tear down the whole env and start from scratch? Painful.

A possible solution: A wget alternative which sends the file url to cache server explicitly. And a customized cache server which can read the param and stream the file from local or internet.

Any idea? Thanks in advance.
