Del.icio.us links in the layout - HELP

I’m trying to get my del.icio.us links to appear in the layout, so it’s
throughout the entire application. Here’s the code I have:

#controller - application.rb?
def get_authenticated(path, http)
request = Net::HTTP::Get.new(path)
request.basic_auth ‘user’, ‘pass’
response = http.request(request)
response.value
response.body
end
@links = Array.new
@descriptions = Array.new
@times = Array.new
@i = 0
http = Net::HTTP.new(‘api.del.icio.us’, 443)
http.use_ssl = true
http.start do |http|
xml = get_authenticated(’/v1/posts/recent?count=10&tag=rpheath’,
http)
REXML::Document.new(xml).root.get_elements(‘post’).each do |post|
link = post.attributes[‘href’]
@links << link
desc = post.attributes[‘description’]
@descriptions << desc
time = post.attributes[‘time’]
@times << time
end
end

#layout - application.rhtml?
<% for link in @links %>

<% end %>

All of this code works fine - I just don’t know where to put it so that
it will show up in a layout that I can use across my application. Any
help on this???

Thanks!
