I have set Cache-Control in apache for 1 week for my JS Files but when i check in the browser Cache-Control shows no-cache. Where i am missing the configuration ?

Below is my configuration in apache

<ifModule mod_headers.c>

  <filesMatch "\.(html|htm|png|js|css)$">
   Header set Cache-Control "max-age=604800, public"
  </filesMatch>

</ifModule>

You need to enable the headers module, assuming debian:

sudo a2enmod headers

then for changes to take effect, you must reload or restart apache:

sudo service apache2 reload

If this does not have an effect, there is also several other parts of your configuration that may override the Cache-Control directive, for example in a .htaccess served from your web root.

Also, I am not sure if Apache allows any capitalisation in your server configuration. Possibly you must use (notice the capital I) and if apache does not recognize your capitalisation, it should print errors when being restarted.

Cache-Control:no-cache does not appear alone, it is being produced by the application.

Whether something is configured in Apache or not, whatever the application returns will override the defaults.

So the besides @MartinOlika answer, the application will have to be reviewed, or if you whish, the desired configuration can be done at application level.
