    r->headers_out.location = ngx_palloc(r->pool, sizeof(ngx_table_elt_t));
    if (r->headers_out.location == NULL) {
        return NGX_HTTP_INTERNAL_SERVER_ERROR;
    }

    r->headers_out.location->value.len = sizeof("http://example.com/") - 1;
    r->headers_out.location->value.data = "http://example.com/";

    return NGX_HTTP_MOVED_PERMANENTLY;
