I need Google indexes full URL with anchor part (http://example.com#!/1234).
User enters on http://example.com/. Then he click a reference and the address of the page changes to http://example.com#!/1234 (something happens, page does not reload). If user types the address (http://example.com#!/1234) directly to address line of a browser and presses Enter then corresponding page loads. It may have differencies from http://example.com (it looks like user has done the action of clicking).
In this case Google can index http://example.com#!/1234 as independent resource.
How to provide the behavior? We have Javascript and any backend language.
See the documentation here: http://code.google.com/web/ajaxcrawling/docs/getting-started.html
And specifically the parts relating to _escaped_fragment_.
