Sometimes it’s desirable to ignore certain values (such as timestamps) for matching purposes. Virtualize is automatically configured to ignore timestamps—based on the following regular expression: 

[0-9]{4}-[0-9]{2}-[0-9]{2}T[0-9]{2}:[0-9]{2}:[0-9]{2}([.][0-9]{1,3})?(([+-][0-9]{2}:[0-9]{2})|Z)?

If you want to review, modify, or add exclusions, click the Exclusions button at the bottom of the page, then edit the values in the table. Element names are specified as exact matches or using a wildcard (*) to match everything. Values are specified as regular expressions.
 

If you always want to ignore certain values for matching purposes, you can enter them once in the Preferences> Parasoft> Traffic File Processing area, and have them applied every time that a parameterized virtual asset is created from traffic. See Traffic File Processing Settings for details.
