I tried to use the WebSpec as provided in the lift packages but ran into an issue running it.
See : https://groups.google.com/forum/?fromgroups=#!topic/liftweb/wpmSCAy4m9U for details.
In the mean time use : https://gist.github.com/2235088 if you want to make use of WebSpec for specs2 (as lift 2.5 now does specs2)
@fmpwizard It looks like you'd originally been meaning to look at this. Do you think you'll have time? If not that's fine, I'll try and make some time at some point this year.
I just assigned it to myself, but if anyone want to look into it, go ahead.
