Download link sends Last-Modified: Thu, 01 Jan 1970 00:00:00 GMT HTTP header

[8u]

How to reproduce:
wget --server-response https://browscap.org/stream?q=PHP_BrowsCapINI

This header makes HTTP agents to save the file with the 1970 modified time:

Workaround until fixed: use --no-use-server-timestamps parameter of wget

1. check StreamHandler is getting the correct metadata value, and is returning it appropriately
2. check if CloudFlare messes with this
