Most web browsers and proxy servers will cache a JPEG image. Thus, the image sometimes will not change even after being reloaded by the browser. To prevent caching, you should configure the server to send the following headers: Expires: 0 Pragma: no-cache If you can not configure the web server to automatically send these headers with the image, you can use a CGI. We have included a Perl CGI and an Active Server Page on the Medusa CD which will send the headers with the image. However, it is recommended to configure the web server (when possible) to save on system resources.
