The Modtronix HTTP server sets JavaScript files to be cached for 10 minutes and all other files to be cached for 5 minutes. This is done with the "Cache-Control: max-age=..." HTTP headers. This has the effect that JavaScript files are only downloaded every 10 minutes, and all other files every 5 minutes. This can be changed by modifying the "http.c" file.
If a web page file should not be cached, it should have to following line in it's header:
<meta http-equiv="Pragma" content="no-cache">
