[Dynamic Parameters]

[Phú Nguyễn]

I have a request like this : 

.get("/socket.io/?EIO=3&transport=polling&t=LRKN9k7&sid=kXq4DLllMFOL0SfOAAEJ")

The thing is "sid" and "t" params will generate a whole new value each time logging in to my site.

So, the question is how to capture those NEW values BEFORE sending the request above (Correlation) ? Since I'm very new to scala, I have been finding out on the internet but there is nothing really clear.
