Framework"},"content":{"rendered":"
A little while ago, while coding <\/a>Bitcoin Pie<\/a>, I found the need to overcome the notorious Same Origin Policy<\/a> that limits the domains javascript running on a client\u2019s browser can access. Via Stack Overflow<\/a> I found a site called Any Origin<\/a>, that\u2019s basically the easiest way to defeat Same Origin Policy without setting up a dedicated server.<\/p>\n

All was well, until about a week ago, Any Origin stopped working for some (but not all) https requests. It just so happened that in that time I had gained some experience with Play! and Heroku, which enabled me to quickly build an open source clone of Any Origin called Whatever Origin (.org!)<\/a> (on github<\/a>). For those unfamiliar with Play! and Heroku, let me give a short introduction:<\/p>\n

Heroku <\/a>is one of the leading PaaS <\/a>providers. PaaS is just a fancy way of saying \u201cLet us manage your servers, scalability, and security \u2026 you just focus on writing the appliaction.\u201d Heroku started as a Ruby shop, but they now support a variety<\/a> of programming languages and platforms including python, java, scala, javascript\/Node.Js. What\u2019s extra cool about them is that they offer a huge set of addons<\/a> ranging from simple stuff like Custom Domains and Logging through scheduling, email, SMS, and up to more powerful addons like Redis<\/a>, Neo4j <\/a>and Memcached<\/a>.

<\/div> <\/div><\/p>\n

Now for the application part, I had recently found Play! Framework<\/a>. Play is a Java\/Scala framework for writing web applications that borrows from the Ruby on Rails \/ Django ideas of providing you with a complete pre-built solution, letting you focus on writing your actual business logic, while allowing you to customize everything later if needed. I encourage you to watch the 12 minute video on Play!\u2019s homepage, it shows how to achieve powerful capabilities from literally scratch. Play! is natively supported at Heroku, so really all you need to do to get a production app running is:<\/p>\n
