Q197817: IIS4.0 Logs Incorrect Value for Time Taken in W3C Extended Log

Article: Q197817
Product(s): Internet Information Server
Version(s): WINNT:4.0
Operating System(s):

-------------------------------------------------------------------------------

SYMPTOMS
========

When IIS logging format is set to W3C Extended Log File Format, you can
customize the format using the Extended Property page in the Extended Log
Property sheet. If you select the Time Taken option, IIS will log the time to
perform the action for every log entry in the time-taken column in the log
file.

The time logged by IIS for the Time Taken option is not accurate. The time
reported for the same file and from the same browser is inconsistent.

CAUSE
=====

IIS depends on the next request to come in for logging the results of the
current request. If you do not have any activity between IIS and the client
browser for a while, IIS will wait until a "connection time out" and then log
the results.

NOTE: IIS calculates the time-taken based on the staring time of the request and
the time when the logging is performed.

RESOLUTION
==========

A supported fix that corrects this problem is now available from Microsoft, but
has not been fully regression tested and should be applied only to systems
experiencing this specific problem. If you are not severely affected by this
specific problem, Microsoft recommends that you wait for the next Windows NT
service pack.
