Ne keverjuk a nyelvet es a nyelv implementaciojat. Nincs mindenki megelegedve a php zend fele implementacijaval,
igy aztan tobb kevesebb sikerrel szuletnek mas implementaciok is.

Taesoo Kim, Ramesh Chandra, Nickolai Zeldovich: Efficient patch-based auditing for web application vulnerabilities [1]
"This paper presented POIROT, a system that can audit
past requests in a web application for exploits of a newly
patched security vulnerability. POIROT incorporates three
techniques—control flow filtering, function-level auditing,
and memoized re-execution—to significantly speed up
auditing compared to previous systems that audit through
re-execution. POIROT is effective at detecting exploits of
real vulnerabilities in MediaWiki and HotCRP. POIROT’s
optimizations allow it to audit challenging patches, which
affect every request, 12–51× faster than the original exe-
cution time of those requests."
