If you don’t need to download certain elements, e.g. images, flash, CSS, during monitoring or you wish to filter out elements that return errors, you can enable network filters and add filter rules to a script using the methods listed below.
The filtering rule with the lowest line position in the script has the highest priority and will be applied to all network requests specified in the script lines above the filter’s line. Similarly, the first filter with the highest line position in the script will have the lowest priority.
