Answer 1

If this question pertains to caching of javascript or css that are a part of your tomcat application directory; you may like to examine the /conf/web.xml file.

Typically the mime mapping available here is

   js
   application/javascript

In apache the default directive is
   ExpiresByType text/javascript "access plus "

You may like to change the apache directive to application/javascript or change the tomcat mime mapping to text/javascript and this will set the expiration to your timeframe.
