what method/algorithm does iis 7 use to generate etags. I'm looking for exact, not 'well they use checksum on the date'
This leaves lots of questions. What algorithm for checksum, which date, which format of the date (short, utc, 'mm-dd-yyyy ttad', 'MMDDDYYY', etc)
Thanks in advance. i have scoured the net and cannot find this answer.

ETag generated by IIS has two parts
Filetimestamp:ChangeNumber

As you noticed, the algorithm is not publicly available. But why you are interested in this? Unless you create an IIS clone.
