In HtmlUnit, can the server see other properties aside from the userAgent?

I am trying to run a few different browsers and my goal is to make each of them appear unique. If I change the userAgent property, I noticed that the applicationName and applicationVersion remains the same, do I need to change those as well?

From what I've gathered, when a request is sent from my htmlunit browser, the userAgent is sent as well but I'm not sure about those other properties.

Would appreciate any help on this.
