IIS 6.0 Log : multiple pageview for a redirect page to d/l a pdf file

[seanbun]

Hi,

I've set up a redirect page (.asp) to download a pdf file. This can track number of people requesting to d/l a pdf file.

i.e. no of pageview = download rate of the pdf file

However, when I see the IIS log file, I found there is multiple (says 5-8 times) of pageview with same session id. In other word, when people download a pdf file, it will generate multiple pageview on the log for one single redirect request.

Do you guys know why?

Are all the request timestamps at the same (or similar) times?

[seanbun]

Yes, all requests were on similar timestamp, less than 1 sec difference

Hi all,

I did some more testings and found this is an issue of MS-Outlook.

When I clicked the link (in an email) to the redirect page in MS-Outlook, multiple records of pageview were found. It seems MS-outlook fired multiple requests.
