I don’t know how you’re supposed to redirect from old sites to new ones but I did it with a simple Sinatra app. I disconnected the previous sinatra app from my domain and connected this and it kinda works!
require 'sinatra'
get '/' do
redirect "http://maxjacobson.github.io"
end
get '/feed' do
redirect "http://maxjacobson.github.io/atom.xml"
end
get '/~about' do
redirect "http://maxjacobson.github.io/blog/about"
end
get '/~projects' do
redirect "http://maxjacobson.github.io/blog/about"
end
get '/:anything' do
redirect "http://maxjacobson.github.io"
end
edit November 2014: I open sourced the app and made a few small tweaks to reflect my current internet home.
