I'm fiddling with middleman 3.0.9 for some time now, trying to create some dynamic output that I need.
Older versions had the "dynamic pages" feature. 3.0.9 does not seem to have something similar. I do not find anything in the docs, nor in the net at the moment.
I simply want the endpoint '/foo' dto do some processing and return some custom data with every request.
How can I achive that?
