Multiple headers are combined into one with the '\n' separator, instead of a comma. 
See: http://trac.webkit.org/browser/trunk/Source/WebKit/chromium/src/WebHTTPLoadInfo.cpp?rev=96981#L108

It is correctly combined with comma in Safari 5.1.

HTTP 1.1 Section 4.2
It MUST be possible to combine the multiple header fields into one "field-name: field-value" pair, without changing the semantics of the message, by appending each subsequent field-value to the first, each separated by a comma. 

Look at the following Cache-Control header:
