Is there a particular reason you want to ignore the query string parameters?
It seems like you are trying to send one response to any request or perhaps, the service is implementing some sort of custom selection criteria.
Some potential ways to address this are:
- Use the copy feature in the VSI to generate additional transactions each having a varying number of query string arguments and set the Comparison Operator for each query string argument to "Anything"
- Change the Operation Match Style from "Signature" to "Operation" and maintain only one transaction in the VSI
