Javascript .js caching problem?

I am noticing a problem with a javascript .js file deployed in my web application. Web AS does not pick up new changes to this .js file. Web AS keeps picking up the older copy of the .js file deployed in a war file. I have deleted the ear file created under and redeployed:

/usr/sap/J2E/JC00/SDM/root/origin/sap.com/myapp/localhost/2005.06.24.08.27.35

Where is Web AS caching the deployed files? Why doesn't the refreshed copy of the .js get deployed? Rest of the application deploys fine except for the javascript file.

Can some one please comment on any similar experience?

Thanks for the help.
