Hrmmm, which version of Chrome is that? I'm running the latest 5.0 beta and I'm seeing the following:
** Using F5 only ** GET /Headers/ HTTP/1.1 Host: xxxxxxxxxxx Connection: keep-alive User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/533.5 (KHTML, like Gecko) Chrome/5.0.378.0 Safari/533.5 Cache-Control: no-cache Pragma: no-cache Accept: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-GB,en-US;q=0.8,en;q=0.6 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 ** Using CTRL+F5 ** GET /Headers/ HTTP/1.1 Host: xxxxxxxxxxxxxxxxx Connection: keep-alive User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/533.5 (KHTML, like Gecko) Chrome/5.0.378.0 Safari/533.5 Cache-Control: max-age=0 Pragma: no-cache Accept: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 Accept-Encoding: gzip,deflate,sdch Accept-Language: en-GB,en-US;q=0.8,en;q=0.6 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 If I remember rightly, the above is also how Firefox handles Cache-Control headers. I've not been able to make Chrome emit two Cache-Control headers on a single request.
