     [ https://jira.jboss.org/jira/browse/JBPORTAL-2399?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Philip Kedy updated JBPORTAL-2399:
----------------------------------

    Description: 
We commonly use the header-content feature of jboss-portlet.xml.  It appears as though if multiple portlet instances of the same portlet definition are on the page that the JavaScript and CSS files referenced in the header-content are included in the head tag multiple times.

This causes several browser performance issues with managing an increased volume of CSS and JavaScript.  Also Internet Explorer has a limit of 32 CSS files that can be referenced directly in the head tag.  Between the theme CSS and portlet CSS it is possible to surpass the 32 file limit.

I have attached a revision to HeaderContentTagHandler.java to prevent multiple references to the same file.  It also writes out references to CSS before JavaScript which is supposed to improve browser performance.
