I’m trying to set up a rule which is going to redirect only every second  
or  
third request only if the URL contains a specific string.  
I did already the redirect based on a string in the URL but I can’t find  
how  
to redirect only every second on third request:

if ($request\_uri ~ ._.WHATEVER\_STRING._) {  
if (this is the 2nd request than) {  
rewrite ^/(.\*) WHATEVER\_URL;  
}  
}
