/etc/design approach - reading from 2 different /etc/design node on same page

 

We have a requirement for universal header and footer. 

 

We have 10 sites. All of these 10 sites will be using same header and footer to make sure all  of them gets same branding experience. One section of header (top part) remains common to all sites and 2nd section of header (lower part) changes from site to site (site1 , site2 , site3....)

 

So for header section we have 2 component:

1. Global Header Component  

- This contains content which is common to all the sites

This stores at /etc/design/global-header

 

2. Site Specific Header Component 

- This contains content which is specific to that site

This stores at :

/etc/design/site1-header

/etc/design/site2-header

/etc/design/site3-header

/etc/design/site4-header

 

What is the best appraoch for handle this situation. I want to use /etc/design so that we do not need to author header for each page. In page property I can assign only one design path (/etc/design/site1-header) so how do i make sure that i include both of the design paths on same page:

/etc/design/global-header

/etc/design/site1-header

 

One way to solve this is to include one design path using page property and second design path include in JSP template using <c:import url="/etc/designs/global-header/jcr:content/global.html"/>

 

All I am trying to do is reduce any duplicate authoring or mainataining common content at more than 2 places.

 

I think this is a classic problem and someone of you must have encountered this scenario.
