I was reviewing my IIS logs and noticed a single IP accessing the same file multiple times within seconds of each other. There are other IP addresses that do the same and cannot figure out why this is happening. This is on a closed network and thought maybe it was a Google Search indexing but they are not GSA's. One request lasted 6 mins and up to ~100 requests within that time period. Their browser agent are what a normal browser would be also. The servers are setup on a cluster with only two servers set to passive/active I believe.
