Usually one would download a file with a URL ending in the file extension.
To download Ubuntu ISO, one would simple
wget http://releases.ubuntu.com/14.04.3/ubuntu-14.04.3-desktop-amd64.iso
However, I came accross a site that I suspect uses ASP.Net / IIS.
A link to a ISO is in this form (I removed link contents incase of ... policies):
http://some.ip.in.here/website.com/IMAGENAME.ISO?md5=hUhpyFjk7zEskw06ZhrWAQ&expires=1454811899
I am not sure how to download this since it has the MD5 and expiry time as parameters, and so wget only downloads a web page, not this ISO.
Any suggestions?
