Incorrect content-encoding on gzip files.

[pbaylas]

If you try to use sendfile with .gz or .tgz files, the response is given the Content-Encoding of "gzip" which causes the browser (or other client) to automatically decompress it on download.

.gz files should have no content-encoding and a content-type of 'application/x-gzip' and .tgz files should have no content-encoding and a content-type of 'application/x-compressed ', I think.

I'm using:

from mimetypes import guess_type

to figure out the content-type of the file.

I think you can use that module to insert the content type you want:
