Redirect not working

[kvelaro]

Hi there, we have been using enhanced_memcache module for a long time.
But it seems it's not working with redirect
So if I put
1.

EXTRACT_HEADERS\r\n
Location: http://www.google.com\r\n
X-Nginx-Status: 302\r\n
\r\n

I get 200 [OK] and no redirect

EXTRACT_HEADERS\r\n
HTTP/1.1 302 Found
Location: http://www.google.com\r\n
X-Nginx-Status: 302\r\n
\r\n

I get 200 [OK] and no redirect

3. (without trailing \r\n)

EXTRACT_HEADERS\r\n
HTTP/1.1 302 Found
Location: http://www.google.com\r\n
X-Nginx-Status: 302

Redirect from backend, not nginx

Thanks in advance?

P.S: Compiled --with-debug, but it seems it`s not outputting debug in logs
