I'm looking to add push notifications to one of my iOS apps. The app is a client for a website which doesn't offer push notifications.What I've come up with so far:App sends a message to home server when transitioning to background, asking the server to start polling the website for the logged in user. The home server starts a new process to poll for that user. Polling happens every so many seconds / minutes.When the user returns to the iOS app, the app sends a message to the home server to stop polling.The home server kills the process polling for the user.Repeat.The problem is that this soon becomes stupid: 100s of users means 100s of different processes. It's just not scalable in the slighest.What I've written so far is in PHP, using CURL to do the polling and I started with PHP a few days ago, so maybe I'm missing something obvious that could help me with this.Some advice would be great.
Scalable solution for website polling
php;ios;server side;push;polling
I don't think PHP is the way to go here, what your writing is backend code. I have written something very similar to this. I used ruby, eventmachine, em-http-request and beanstalkd. It worked well and was dead simple.
