The issue with the Content-Type being sent with the 304 response has been resolved. It appears that the issue was with the configuration of the host providers Apache setup. They moved the website onto a different server and the problem went away. I have not had confirmation but I think it was because they had a DefaultType set in the httpd.conf but also the new server is running a newer version of Apache so I can't be sure but it also may have been a bug in Apache 1.3. So I have moved away from using NPH and no longer have to worry about the Keep-Alive issue as that functions correctly in non NPH mode. Many thanks for your help.
