Is your feature request related to a problem? Please describe.
Currently, the add-on supports the JSP, Html based Scan Rules, PHP so now we need to add the ASP-based scan rule. This Feature/Enhancement is for that.

Definition of Done
Definition of Done for this scan rule is

1. Adding various scan rules for ASP, ASP in images, etc.
2. Adding a VulnerableApplication which supports the https://github.com/SasanLabs/VulnerableApp-facade so that we can do TDD type of implementation where Vulnerable applications are written first and then Scan rules are written over them.
