Why GUID as part of css Link (href)?

I'm reviewing an existing ASP.NET Web app, and at one point the code
programmatically determines the css file name (and path) to be sent to the
browser to be included in the markup of the current page.

In addition to rendering the path to the css file, the code appends "/" + a
new GUID value... like this:

UserControls/Styles/StyleSetThree.css/21454a5c-bc5e-4d56-9354-34db01351512

Question: Why the GUID like this? What does having a unique value do?

Thanks.
