update: solve problem using query string, after reading how regex , .htaccess rewrite url

rewritecond %{query_string} ^w=([a-za-z0-9]+)$ rewriterule ^/*buy/$ http://anotherdomain.tld/product.php?id=%1 [nc,l,r=301]

thank stackoverflow , folks! m start understanding regex here ^_^

that's right, params won't picked up, can passed on.

something like;

rewriterule ^buy/([a-za-z0-9]+)$ http://anotherdomain.tld/product.php?id=$1 [nc,l,r=301]

where original url be; /buy/x1234
