Dynamic Headers for Open Graph tags in E-Com site
Hi,
I have an E-Commerce site. Im using a Template hierarchy. With the top
template containing the Open Graph tags for the entire Site.
Like
The issue is there are PRODUCT PAGES that extend this template. But for
Products its desirable to insert PRODUCT SPECIFIC headers.
What is the cleanest way to do this?
Note I can do this in a Dirty Way: If I use "IHeaderContributor" in the
Product Page then it will "APPEND" it not replace the template tags. .. and
removing thsi from the base template and Providing it for each page does not
seem good either.
..Anyway I can demarkate this and override?
thanks

My panel had all meta tags for all possible data.
Each page constructs some data (a model) depending on the current
functionality.
Then the panel uses the model to populate some of the meta tags and to set
invisible all without data for them.

Thanks ..so using Panels in the <header> did work out fine. .. using
container !
Though; I want to put custom variables in the META tags; I found it more
complex it to do via Wicket.
Rather used Velocity to accept a MAP of Attributes and generate the META
TAGS and pass that into a FRAGMENT seemed scalable and faster.
But curious if you dumped the entire META content is a String or you used
Some sort of Repeater or Wicket component to render the Dynamic individual
Meta tags?
Example in Velocity I found to be a breeze over wicket:

This is exactly how I did it once - use a normal Panel in the header
section:
<head>
...
<wicket:container wicket:id="openGraph"></wicket:container>
...
</head>
And then a base Page has a method that adds the panel if the current page
constructs non-empty model.
Simple.

I think I'll take a simple approach.
Use a Spring Resource to read a file which contains only the OG Tags and use
EhCache to cache the content.
I'll remove the OG Tags from the Common Template and instead inject it
dynamically then
For product pages the OG tags have to be created per request so override the
header contribution for this part and insert the Product Specific OG Tags.
Like we have Panels in the Body section, why cant we have a concept like
that for the Header?
Anyway
