How to let ajax request be cached?

It requires a little bit more work, but you can specify that your AJAX queries be GET.

See:

[http://www.mnot.net/blog/2006/08/14/webizing_ajax](http://www.mnot.net/blog/2006/08/14/webizing_ajax)

for a description of the javascript.

Within rails, you probably want the :method parameter, eg.

form_remote_tag :method => 'get'
