location = ngx\_palloc(r-\>pool, strlen(url));  
…  
r-\>headers\_out.location = ngx\_palloc(r-\>pool,  
sizeof(ngx\_table\_elt\_t));  
…  
ngx\_copy(location, url, strlen(url));  
r-\>headers\_out.location-\>value.data = location;  
r-\>headers\_out.location-\>value.len = strlen(url);  
r-\>headers\_out.content\_length\_n = 0;

Ok. Follow code work:

header = ngx\_list\_push(&r-\>headers\_out.headers);  
if (header == NULL) {  
return NGX\_HTTP\_INTERNAL\_SERVER\_ERROR;  
}

header-\>hash = 1;  
header-\>key.len = sizeof(“Location”) - 1;  
header-\>key.data = (u\_char \*) “Location”;  
header-\>value.len = sizeof(“[http://google.com/](http://google.com/)”) - 1;  
header-\>value.data = (u\_char \*) “[http://google.com/](http://google.com/)” - 1;
