How does Webtrends filter or display URLs where parameters are in a different order on different hits?

Cause

URLs contain two or more parameters similar to the example below and the order of these parameters may change. There is concern that the filters on the profile may not function or that the URL may be split into multiple URLs in the reports.

For example:

http://www.domain.com/folder1/page1.aspx?A=value&B=value

and

http://www.domain.com/folder1/page1.aspx?B=value&A=value

Resolution

Webtrends parses the parameters separately and reorders them first numerically then alphabetically to ensure there is a single representative URL in the reports and uniform filtering. As a result, filters will not miss the affected URLs and URLs will not be split into multiple URLs for the same page due to parameter order.

The above example would show a single URL with two page views in the Pages report, as follows:

http://www.domain.com/folder1/page1.aspx?A=value&B=value

If the parameters have numbers in the name similar to the following example:

http://www.domain.com/folder1/page1.aspx?B=value&A=value&2=value&1=value

…then the URL would be reordered in the reports numerically and alphabetically, as shown below:

http://www.domain.com/folder1/page1.aspx?1=value&2=value&A=value&B=value
