What information should I put in the user-agent for my private application

I have an intranet application that call public websites to get the title of the webpage. For exemple, when one of my user add an url to a form, I have a WebClient that call the the url website to read the <title> tag of the web page.

I would like to know what information I should put in the user-agent. What I've read on many blogs, is that the minimum of information shoud be:

• the name of the application
• the version of the application
• a public web page to explain what this application is doing

So an example of this would be ApplicatioName/1.3 (+https://somesite.com/bots/applicationame.html)

Here's my questions:

• My web application is private on the intranet network so I cannot put public information easly about my application and the WebClient. What should I do?
• Is there some other kind of information I should put in the user-agent to be "politicly correct" when I call a web site and explain why if possible
