Router is wrong?

Question

Apache HTTP Server

RewriteRule ^check/$ /index.php?folderName=catalog&scriptName=check/index [L,QSA]

why does not it work? the rest is all right, I copy the line, I replace the names (where check is written) and the router does not work, at the check address I will write nothing else, something else will work immediately

Answer 1

As the rule was written, so be it. If the slash is optional, then write this:
^check/?$
