Not sure what is "Category.all" in your "each" enumerator.
Try this, assuming CACHE.featch ''all_categories'' is returning
an array of
sorts:
<% CACHE.fetch(''all_categories'').each do |category| %>
<ul>
<li><%= category.name <http://c.name/> %> </li>
</ul>
<% end %>

You could try changing it to a < %= but I''m not sure that mixes well with yielding to a block or the case when it is generated fresh data. Why not use cache_fragment ?

You are right.. changing it to the following throws a nasty syntax error. <%= Rails.cache.fetch "all_catgory" do %> <!-- generate html for categories --> <% end %> If I do <% cache(:key => ''all_category'') do %> <!-- generate html for categories --> <%end%> The it does work, BUT..somehow the page url is prepended to the cache key so essentially this fragment which is same across the app, misses for every new page load.
