Not reflecting the changes - header footer

Hi All,

   I have found that exo-ecm application is using  '<EXO-HOME>\webapps\resources\community\web-content\banner.html' as header,  '<EXO-HOME>\webapps\resources\community\web-content\footer.html' as footer.

 ISSUE: The changes done to these pages are not reflecting to the page until clean the DB and re-create it. If any one knows how to resolve this, please let me know the solution

Thanks in advance...
