Issue

  • Cache-Control header is not present in static resources when running the portal from Developer Studio and setting com.liferay.portal.servlet.filters.header.HeaderFilter=true property in portal-ext.properties does not help.

Environment

  • Liferay DXP 7.1
  • Liferay Developer Studio

Resolution

  • The issue is present when developer mode is turned on in Liferay Developer Studio. Turning it off and commenting out include-and-override=portal-developer.properties in portal-ext.properties solves the problem.
  • To turn developer mode off: Select the Liferay 7.x server in the Servers window. In its Overview, under the Liferay Launch untick 'Use developer mode'.

Additional Information

  • The following property is set in portal-developer.properties by default and is responsible for the issue: 
    com.liferay.portal.servlet.filters.header.HeaderFilter=false
