I am using Apache HTTPD 2.2 on Windows. mod_expires is commented out. Most other stuff are not changed from the defaults. gzip is on.

I made some changes to my .js files. My client gets one 304 response for one of the .js files and never gets the rest. How can I force Apache to sort of flush everything and send all new files to the client?

The main html file includes these scripts in the head section of the main page:

    <script src="js/jquery-1.7.1.min.js" type="text/javascript"> </script>
    <script src="js/jquery-ui-1.8.17.custom.min.js" type="text/javascript"></script>
