...If you are using a regex-based route, find-my-way will throw an error if detects potentially catastrophic exponential-time regular expressions (internally uses safe-regex2). According to RFC3986, find-my-way is case-sensitive by default. You can disable this by setting the caseSensitive option to false: in that case, all paths will be matched as lowercase, but the route parameters or wildcards will maintain their original letter casing.
