what does "?" in /content(/.*)? mean???
1 Accepted Solution
Correct answer by
This is regular expression. ? makes the pattern in () optional. To explain it further, if you use "?", all paths under /content are valid(including /content as well) but if you dont use "?" then "/content" is not allowed.
/content [Invalid when "?" is NOT there]
/content/a [Valid in both]
/content/a/b [Valid in both]
