There's indeed some interesting magic going on:


$ lwp-request -m HEAD -U libraries
HEAD http://www.libraries.at
User-Agent: lwp-request/5.827 libwww-perl/5.832

200 OK
[..]

$ lwp-request -m HEAD -U http://libraries
HEAD http://libraries
User-Agent: lwp-request/5.827 libwww-perl/5.832

500 Can't connect to libraries:80 (Bad hostname 'libraries')


The second one is expected but the first one, where "libraries" is
converted into "http://www.libraries.at" for me (and something
similar for you), is - hm - a bit 'user-friendly'.

I don't think it's a problem related to resolv.conf but the
missing schema:// where libwww-perl adds stuff to make a complete
URL.

I'm just not sure where and why this is happening ...
