Sinatra is not persisting my session with a redirect on Chrome. It is creating an entirely new session and i'm losing all my previous session data. As an example (similar to the Sinatra docs ), i'm doing something like this: enable :sessions get '/foo' do session[:user_id] = 123 session[:session_id] # "ABC", for example redirect to('/bar') end get '/bar' do # this is "DEF" when responding to Chrome (wrong), # but "ABC" when responding to Firefox or Safari (right) session[:session_id] # this is nil when responding to Chrome (wrong), # but 123 when responding to Firefox or Safari (right) session

Gollum is "A simple, Git-powered wiki with a sweet API and local frontend." It's hosted on GitHub: http://github.com/github/gollum It seems to be a simple Sinatra app, and as such, it seems like it should be easy to deploy to Heroku. I can't seem to get it to work. Mostly because I know next to nothing about Rake and config.ru files. Is it even possible to deploy a Gollum wiki to Heroku? If so, what would my config.ru file need to look like? Update/Edit lib/gollum/frontend/app: module Precious class App < Sinatra::Base This gets called from bin/gollum require 'gollum/frontend/app' Precious:

I want to send binary data from a Sinatra application so that the user can download it as a file. I tried using send_data but it gives me an undefined method 'send_data' How could I achieve this? I could write the data to a file and then use send_file but I would rather avoid doing this. you can just return binary data: get '/binary' do content_type 'application/octet-stream' "\x01\x02\x03" end I did it like this: get '/download/:id' do project = JSON.parse(Redis.new.hget('active_projects', params[:id])) response.headers['content_type'] = "application/octet-stream" attachment(project.name+'

I'm trying to get the domain name in my Sinatra app but as a newbie I really am struggling to figure out how to do this, and I know it must be possible! Rack::Request#host_with_port looks promising, but I don't know how to get this from my app - how do I get stuff from Rack in my Ruby code? Or is there another way - I'm thinking I don't really want to do this every time a request happens (although it's not too bad), but I thought it'd be better if I could just do it once when the application loads up. Any hints? simply use request.host inside your code. get "/" do puts request.host #=>

I'm looking for a robust way to deploy a Rack application (in this case a Sinatra app). Requests will take a little time (0.25-0.5 sec waiting on proxied HTTP requests) and there may be a decent amount of traffic. Should I go with a traditional mongrel cluster setup? Use HAProxy as a load balancer? nginx? rackup? What solutions have you used and what are the advantages? Nginx / Unicorn FTW! Nginx in front to serve static files and unicorn to handle Sinatra app. Benefits: Performance, good load balancing with unix socks and deploy/upgrade without any downtimes (you can upgrade Ruby/Nginx
