multiple sessions on Sinatra use Rack::Session::Pool

multiple sessions on Sinatra use Rack::Session::Pool

[donhill]

Hi.

Sinata - 1.3.1
Rack 1.3.5

I am experiencing what appears to be multiple sessions on a sinatra
app. I am using Rack::Session::Pool. This doesn't happen all the time
but the same customer has complained they keep getting an exception.
The flow is like this.

I am using default settings for the Pool

goto registration page
submit the page - I set a session value here
the user goes to a verify page and selects edit, when returning to the
registration page the session is empty

I am dumping the session and cookies in my logs and it seems the
session cookies have changed values

Has anyone experienced this tell me how to debug this?

Thanks for the read. I will persue this further.

Is there a was for me to debug Rack to figure out if this is actually happening?
