headtags switch
Switch the headtags for specified pages
This script goes in your _headtags file
The entries in $alt_headtags_pages should be just enough of the url to uniquely identify a single page a folder of pages or even a subdomain
Use a pipe symbol | to mark the end of an entry
Using {{...}} the entries can be on separate lines
The : are just padding for the loop
Note: subdomains should have an additional entry as a folder of the main site
This is because
<xt:url>
will not return a subdomain for http://subdomain.site.com without a page specified in the url ie: http://subdomain.site.com/index Example code
