This feature deserves to be extended :-)
I have the mime type and the content charset in mind.
BTW, what is the 'cost' for this feature regarding disk space ?

Hi,
I find it useful to keep track of where files are downloaded from. POSIX
extended attributes provide a lightweight portable method of keeping this
information across Linux, OS/X, FreeBSD and many other platforms.
This compliments wget's existing WARC support, which serves a related but
different use case closer to tcpdump or tar for web pages. Extended
attributes can provide a quick answer to "where did I get this file from
again?"
This patch changes:
* autoconf detects whether extended attributes are available and enables
the code if they are.
* The new flags --xattr and --no-xattr control whether xattr is enabled.
* The new command "xattr = (on|off)" can be used in ~/.wgetrc or
/etc/wgetrc
* The original and redirected URLs are recorded as shown below.
* This works for both single fetches and recursive mode.
Here is an example, where http://archive.org redirects to
https://archive.org:
$ wget --xattr http://archive.org
...
$ getfattr -d index.html
user.xdg.origin.url="https://archive.org/"
user.xdg.referrer.url="http://archive.org/"
These attributes were chosen based on those stored by Google Chrome (
https://bugs.chromium.org/p/chromium/issues/detail?id=45903) and curl (
