[eankit]

I'm very confused right now, I don't know how to block or redirect a specific QUERY STRING url via .htaccess file, well actually I want to redirect this type of url :

test.php?q=RANDOMTEXT=&tl=The%20path%20ends
to
example.com/newwebpage.html

If anyone knows how to solve this issue please let me know and thank you in advance
