hi all, 


Who can help me understand why the highlighted is not&nbsp; toupper(aa) == toupper(bb)&nbsp; or tolower(aa)==tolower(bb)&nbsp; ?


in file ModSecurity/src/variables/variable.h


class VariableMonkeyResolution {
&nbsp;public:
&nbsp; &nbsp; VariableMonkeyResolution () { } 
&nbsp; &nbsp; static inline bool comp(const std::string &amp;a, const std::string &amp;b) {
&nbsp; &nbsp; &nbsp; &nbsp; return a.size() == b.size()
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;&amp;&amp; std::equal(a.begin(), a.end(), b.begin(),
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; [](char aa, char bb) {
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; return toupper(aa) == bb; 
&nbsp; &nbsp; &nbsp; &nbsp; }); 
&nbsp; &nbsp; }&nbsp; &nbsp;



thanks
