[Rails] Re: Storing Rails controller callback data in session

Hi, and yes, 

I agree this is not a valid solution for production environments at all.

However, when without many resources, e.g. experimenting, there is no "free" option to support such architecture.

E.g. on Heroku you need some funds to have 1 web server and 1 background worker.

Also, I really don't like the idea of setting up such environments in development.

Hence, I wanted to see if there way a "cheap and dirty" way of doing this.

And, to my surprise, session is not being updated as expected.

I also get the feeling there is some important bit of knowledge to be gained with deep understanding of this behavior or Rails.

So, I'd still like to know why Rails behaves this way...

Thanks for the input!

This sounds like a bad idea right out of the gate. My suggestion is to
put the whole thing out of your mind.

If you have a "time consuming action" then use one of the established
backgrounding solutions that are available:
