Since the third parameter is optional, solved it as follows:
RewriteRule ^([a-zA-Z0-9\.]+)/([0-9\.]+)/?(.*)/(.*)$ m.pl?id=$1&cv=$2&cu=$3&qty=$4
Pergunta
This is my .htaccess rule:
RewriteRule ^([a-zA-Z0-9\.]+)/([0-9\.]+)/(.*)/(.*)$ m.pl?id=$1&cv=$2&cu=$3&qty=$4
So, a link like cpa/11/axg/4
gets redirected correctly.
But if the 3rd value is blank, i.e.
cpa/11//4
, it does not get redirected to the rule defined above.
I am not sure how to address this.

You can have 2 separate rules to address this:
RewriteRule ^([a-zA-Z0-9.]+)/([0-9.]+)/([0-9]+)/?$ m.pl?id=$1&cv=$2&qty=$3 [L,QSA]
RewriteRule ^([a-zA-Z0-9.]+)/([0-9.]+)/([^/]+)/([^/]+)/?$ m.pl?id=$1&cv=$2&cu=$3&qty=$4 [L,QSA]
