Hi Paul,

I'm using it quite a bit in my OWASP Summer of Code project; here's the Wiki:
http://www.owasp.org/index.php/OWASP_Securing_WebGoat_using_ModSecurity_Project

Section 4 has a part on using Lua script; check out "Sublesson 4.2: Forgot Password" at the bottom of the page if you are further interested:
http://www.owasp.org/index.php/OWASP_ModSecurity_Securing_WebGoat_Section_4_Mitigating_the_WebGoat_Lessons I implement a rudimentary but configurable account lockout mechanism using Lua persistence.

Combined with content injection that uses Javascript (prepend & append to the response body), almost anything can be done because I have available to me one programming language on the front end and one on the back end.

I see its biggest value in virtual patching especially when the results of a pentest come in, the discovered vulnerabilities need to be mitigated, and the application cannot be touched. A human will find business logic flaws (whereas a vulnerability scanner never will) and the combo of Lua script & js content injection allows for flexibility in mitigating them (automation cannot help here). Whether it's practical or not in the real world is not my concern at this point in time; my goal is to fix the vulnerabilities in WebGoat and I'm using the functionality that is at my disposal.

Stephen
