[Nginx Config] rewrite host

[CactO_o's]

Hi all,

I test to rewrite the sub-domain in /etc/nginx/site-available/default and I would know if exist a function for add GET argument ?


For example :

if( $host ~* "(.*)\.*\.{2,4}" )
{
    addGet sd $1;
}


This code add "?sd=$1" or "&sd=$1" (if there are already arguments GET before or not)

If not exist how can I do that ? 

Thank you and sorry for my english (I'm french :p)
