Re: Getting 200-302-304 warnings in the Result logs ??
The "304 Not Modified" response means that the browser used cached files during the recording. TestComplete does not use the browser's cache. So, you may need to re-record your task clearing the cache. See the Traffic Recording article for details.
The "302 Not Modified" response indicates that your server returns a redirect during the recording or playback. There is no particular reason for this behavior. You need to analyze the recorded traffic and logs to find the cause of this.
