I've been poking around with wget to grab a static copy of the https://2015.ploneconf.org site to serve it with nginx.
Googling around I found http://www.linuxjournal.com/content/downloading-entire-web-site-wget and so the command I've used is
wget --recursive --no-clobber --page-requisites --html-extension --domains 2015.ploneconf.org https://2015.ploneconf.org
You can see the static copy at https://2015new.ploneconf.org/ (though any links on that page are not rewritten to use 2015new.ploneconf.org)
This does seem to grab everything correctly, but I've noticed that links to, say, the Things To Do, at https://2015.ploneconf.org/venue/#things-to-do are not correctly converted to use the .html, i.e.. you get an error 403 because the static URL should really be https://2015new.ploneconf.org/venue.html#things-to-do (and sure enough the venue.html page was grabbed by wget)
Plone is smart with its traversal... it just figures out that "venue#things-to-do" is not a directory but an anchor within a page.
Any suggestions on how to handle that sort of Plone URL with nginx?
