Thank you.

My configurations were:

1.

root /path_to_root1;

if ($remote_addr = xx.xx.xx.xx) {

set $document_root /path_to root2;
}


2.

map $remote_addr $document_root {

default /path_to_root1;

xx.xx.xx.xx /path_to root2;

}


3.

geo $document_root {

default /path_to_root1;
xx.xx.xx.xx /path_to_root2;
}



I tryed the three ways you suggested but nginx always answered:

nginx: [emerg] the duplicate "document_root" variable.


My configuration would be to have one document_root for a specific IP and another for the rest of the world.

Did i make any mistake in my configuration?

thank you
