What do your apache logs tell you that apache is actually serving up in these 
cases? If a request fails it should be logged in (the default location) 
/var/log/httpd/error_log, and if you have logging enabled the successful 
requests will be logged in /var/log/httpd/access_log.

If that doesn't show anything useful, run ethereal and capture the transfer to 
see what request is coming in from the client, and what response is being sent 
back by the server.
