I'm pretty sure that wapplyzer perform lowercases matchs.
Note these web links:
"<link [^>]*?href=\"?[a-z]*?:?//cdn\\.statically\\.io/"
"<small>SquirrelMail version ([.\\d]+)[^<]*<br \\;version:\\1"
"<input type=\"hidden\" name=\"shopid\""
HTML specify tags are case insensitive.
Another example for detecting PHP:
"X-Powered-By": "^php/?([\\d.]+)?\\;version:\\1"
In facts, php retruns this header:
x-powered-by: PHP/7.3.27
So the regex match only in case insensitive.
Note this line in the wappalyzer sources:
https://github.com/AliasIO/wappalyzer/blob/557bed87113c8f7073a733d85bb9c7cdb67132c3/src/drivers/webextension/js/driver.js#L49
It seems this bloc of code compiles regex, it uses the flag 'i'.
