AngularJS application hosted on Github pages (gh-pages) ajax crawling

anyone knows if is possible to make an AngularJS with client-side
navigation crawlable by search engines if it is hosted on Github?
Let's say, my application has 3 client-side urls:
http : //my-example-application.com/#!/home
http : //my-example-application.com/#!/documentation
http : //my-example-application.com/#!/download
These URL's will not be seen by the search engines because they are served
on the client side, but according to Google Ajax applications
recommendations to help search engines the dynamic content generated by a
javascript application could be cached previously, so the crawlers would
search for a cached version of the previous pages on these URL's:
http : //my-example-application.com/?_escaped_fragment_=/home
http : //my-example-application.com/?_escaped_fragment_=/documentation
http : //my-example-application.com/?_escaped_fragment_=/download
This could be accomplished via url rewriting on a web server, but do we
have any alternative if we are hosting the dynamic page on Github?
