URL Truncation Parameter

SDC uses this parameter to overcome a maximum URL length limitation imposed by Internet Explorer (Microsoft Knowledge Base Article – 208427). The URL length must be 2048 or less. If the WebtrendsJavaScript tag generates a URL in excess of 2048 characters and the client browser is Microsoft Internet Explorer, the hit is truncated and is passed to SDC.

WT.tu

WT.tu=1

SDC generates this parameter and sets it to 1 if the URL was deemed too long and truncated by the JavaScript tag. If present, SDC writes an error and discards the hit.

You can configure the logtruncatedhits setting to log the truncated hit rather than discard it.
