Some extensions actually consist of multiple parts, like .tar.gz, so we
should handle this properly instead of merging part of the extension
with the bare name. Right now only tar is allowed, but others can be
added easily.
Fixes#74.
Add a middleware that requires authorization for all POST, PUT, and
DELETE requests. This is done using the Authorization header and the
provided auth key is then checked against a file containing scrypted
auth keys. These keys are salted the constant string `linx-server`.
HTTP status code 301 is for a permanent redirect, which these are not.
Although 302 would work here in most browsers, it would not follow the
HTTP spec, so instead we use 303 which has a clearly and consistently
defined behavior in response to a POST or PUT request.
This is a better way to do things since we were customizing middleware
and everything anyway. It's also necessary in order to avoid pulling in
the default Goji -bind flag: https://github.com/zenazn/goji/issues/47
This should protect against cross-site request forgery without the need
for cookies. It continues to allow requests with Linx-Delete-Key,
Linx-Expiry, or Linx-Randomize headers as these will not be set in the
case of cross-site requests.
