How can I set systpl using .htaccess?

 

I tried:

RedirectMatch 301 ^/clientes/(.*)$ https://www.mydomain.com/clientes/$1&systpl=default2

 

but when proceed to order I am redirected to https://www.mydomain.com/clientes/cart.php/clientes/cart.phpsystpl=default2?a=add&pid=2

 

I use joomla un main site and whmcs is installed in "clientes"

 

hope some one can help me with this

Are you just trying to define a particular order form, for specific product groups?

 

If so, this is available in 5.2.x

I don´t understand your answer... I want to set the template (systpl) in the url using .htaccess

 

of course the systpl set with htaccess is not the default systpl, and I want to set different systpl for some products

SOLVED

 

I used:

RewriteRule ^clientes/(.*)$ https://www.mydomain.com/clientes/$1?systpl=default2 [L,QSA]

 

what really I am doing is to set system template in url due to I have a main website (where I use whmcs) and other international web sites (for some countries) and the systpl is set for usability purposes
