we work with webapps, and since these cannot be crawled, we cache html content to serve to search engines.
For this we place the <meta name="fragment" content="!"> tag in the content as google's best practise.
content for that url is then available for crawlers on: www.mydomain.com?_escaped_fragment_=#
so add: ?_escaped_fragment_=# behind the urls to get the html cached version that includes all meta needed for GSA SER.
This would save us a whole lot of time, probably easy to implement, and i guess is a feature that will be more and more appreciated.
