Question

I have built an http module that detect file openings. I don’t want any alert to be raised when the file is crawled by a system account like ‘search’ for instance. I have tried to use isApplicationPrincipal and several others but it didn’t work.

How would you do to keep only track of “real” users modifications ?

Thank you

The SharePoint search index crawler uses “Robot-something” as HTTP user agent. I don’t know what the exact string look like, sorry for that.

You can check if the HttpRequest.UserAgent property contains “Robot”:

if (HttpContext.Current.Request.UserAgent.IndexOf("Robot", StringComparison.OrdinalIgnoreCase) == -1)
{
  // Code that runs for real users only.
}
