IIS4.0 Logs Incorrect Value for Time Taken in W3C Extended log Format

ID: Q197817

The information in this article applies to:

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.
