What is CavalryLogger and do I need it?

By | April 4, 2018

I’m doing some optimisation on a site Ive recently taken over. I’ve found a script I don’t recognise:

It could be a facebook thing, and there’s some key logging going on (that Im not too keen on)

It is without a doubt the largest file being requested on a page load (87kb) so if I can do without it, it’ll really speed up the page load.

Does anyone know:
A) What it is
B) What it’s for
C) What it does
D) Can I do without it
