I want to transfer  
/script/action/var1\_\_\_val1/var2\_\_\_val2/…/varN\_\_\_valN/ to  
/script/action?var1=val1&var2=val2&…&varN=valN. My rewrite rules are:

rewrite ^/script/(._)/(\w+)\_\_\_([^/]+)/(._)$ /script/$1/$2=$3&$4? last;  
rewrite ^/script/(\w+)/(.+) /script/$1?$2 break;

If value of val1/val2/…/valN is alphabets or digits, the rules works  
fine. Once url encoded value appears, the apmersands connecting  
variable-value pairs are escaped to ‘%26’ which makes it sucks.

Can somebody help me?

Thanks, Kenny.
