I'm doing some work with SharePoint online, specifically, and am trying to get a handle on the "UserAgent" field. I keep seeing agents which I would like to try and clarify what they are doing or why they appear, hopefully someone can help?
OneDriveMpc-Transform_Thumbnail/1.0 - Assume this is when the document is previewed?
OneDriveMpc-Transform_Zip/1.0 - I see this appear multiple times against the same document with the same time stamp.. any ideas?
As the user agent is a free text string and can change at any time (or be spoofed), I wouldnt rely on this. I'm not aware of any list that Microsoft published on the above anyway, so all we can offer is some educated guess.
