i have rails app on heroku , need create reverse proxy our blog, hosted on dreamhost. hosted @ blog.ourdomain.com want ourdomain.com/blog point it. research seems best reverse proxy via nginx component of our passenger application server. so, i've created location in our nginx.conf.erb : location ^~ /blog { proxy_pass https://blog.ourdomain.com; } this works fine our purposes, except when /blog visited. ( /blog/ , /blog/whatever/... fine). when /blog used, nginx instead redirects ourdomain.com:12345/blog/ port assume our heroku dyno's port. how can slash-less uri go reverse proxy correctly? i've run same problem well. still haven't gotten our proxy functioning - running weird redirect loops on wordpress / apache side - did solve manually setting port: location ^~ /blog { proxy_pass https://blog.ourdomain.com:80; } i'm not confident enough in nginx knowledge work sure, seems working us.

starting working on new meteor app, have done node.js projects callbacks or promises handle async code going through meteor tutorials; async methods have no callbacks or promises. how handled? example code tutorial: var party = parties.findone(partyid); if (!party) throw new meteor.error(404, "no such party"); if (party.owner !== this.userid) throw new meteor.error(404, "no such party"); if (party.public) throw new meteor.error(400, "that party public. no need invite people."); how can fetch db , perform operations on party meteor uses magical abstraction coroutines called fiber. works same async/await in many other languages. desribe possible: there callbacks underneath, don't need handle them hand. https://github.com/laverdet/node-fibers /edit there great article on meteorhacks describing how fibers work: https://meteorhacks.com/fibers-eventloop-and-meteor
