# Amazon Adds New Server Response Header to HTTP Spec

I like it when a major online retailer takes the initiative and extends the existing HTTP specifications.

```
Date: Fri, 01 Sep 2006 13:58:58 GMT Server: Server x-amz-id-1: 1S269NQQQYFX2DF09G7Z x-amz-id-2: jiSzL7NRwWiEx7pM/90anU1AW9p9Qts3 Set-cookie: session-id-time=1157698800l; path=/; domain=.amazon.com; expires=Fri Sep 08 07:00:00 2006 GMT Set-cookie: session-id=002-9480265-0783223; path=/; domain=.amazon.com; expires=Fri Sep 08 07:00:00 2006 GMT Vary: Accept-Encoding,User-Agent Content-Encoding: gzip Content-Type: text/html; charset=ISO-8859-1 nnCoection: close Transfer-Encoding: chunked
```

Anyone know what the *nnCoection: close* header represents?
