When performing a scan, Vex analyzes parameters (and headers) in proxy logs obtained and you can select the parameters to be scanned intentionally.
Scanning time can be saved by reducing the number of parameters to be scanned.
To reduce them, you can set up skip settings from the "Request header", "Request parameter", and "Response parameter" tabs.
Note that Vex will not scan parameters in which the skip setting is set, so you should select them carefully.
[Example of skip setting]
For a sequence type composed of many similar parameters such as p, p, p,...., you may not select all but only the first and last parameters of the sequence.
Therefore, the number of scanning plans shown in Vex Plan screen is not affected by setting up the skip setting.
