Details:

The WebServer app uses GSMimeDocument class to pack http response,
and also use GSMimeHeader class for HTTP header.

The GSMimeHeader`s -rawMimeData method internally calls [self
rawMimeDataPreservingCase: NO foldedAt:78].

I expect:

 HTTP/1.1 200 OK
 Date: Thu, 20 Feb 2014 00:40:53 GMT
 Set-Cookie: fdfdfdfdfdfdffff ff ffff ..(78byte length).. fffff fffff ffffff
 Other-Header: xxx

But produced HTTP Header :

 HTTP/1.1 200 OK
 Date: Thu, 20 Feb 2014 00:40:53 GMT
 Set-Cookie: fdfdfdfdfdfdffff ff ffff ..(78byte length)..
       fffff fffff ffffff
 Other-Header: xxx

This behavior may make some web browsers to confuse parsing.
The example above breaks cookie value.
