I'm thinking of creating a visitor session recording application for my websites/products, similar to smartlook.com sessionrewind.com fullstory.com
I did a research about the technology or frameworks that can help me in achieving this, but I didn't found relevant results.
I'll be having a small JS code which will keep on sending events to backend server, so as to not have an overload on the browser for processing.
Please guide which framework is used behind these session recording applications. Given a choice I'd like to program in Java/Scala, use Spring/SBT for backend and use pure JS or JQuery for frontend.
