When there is no HTTP_HOST variable, code like <b>Hello <%= @name %></b> <% cache do %> All the topics in the system: <%= render_collection_of_partials "topic", Topic.find_all %> <% end %> returns a "undefined method "+" for nil:NilClass" exception. I''d hate to write code like: <% foo=capture do %> All the topics in the system: <%= render_collection_of_partials "topic", Topic.find_all %> <% end %> <b>Hello <%= @name %></b> <% if @request.env[''HTTP_HOST''] %> <% cache do %> <%= foo %> <% end %> <% else %> <%= foo %> <% end %> How do the others here handle this? -- Justin Dossey
