I was curious as to why the following wget returns a 403/forbidden. The base url is accessed via the ff/chrome browser.. As far as I can tell/see, the cmd should match what the network is seeing regarding the headers/traffic.
wget -vvv --user-agent="Mozilla/5.0 (X11; Linux x86_64; rv:38.0) Gecko/20100101 Firefox/38.0" --cookies=on --load-cookies=aa.lwp --keep-session-cookies --save-cookies=aa.lwp --referer http://coursebook.utdallas.edu
