Subject RE: [users@httpd] Enquiry about Reserve Proxy
Date Tue, 11 Dec 2007 13:09:26 GMT

Hi...

there is no HTTP 404 return in my access log. From the log file, seems like
thing works perfectly.
but I relise that all jpeg images can't be rendered. I have check in the
mime type config file, i can see there is mime type for jpeg (image/jpeg
jpeg jpg). I am able to render all gif images.
any idea what's wrong with my web server configuration?

regards,

Pdt
