Asset_host with HTTPS problem, or possibly layout being cached?

Rails

I’m having some trouble with either the asset_host feature or possible
something to do with layout caching.

I have this in my environment/production.rb:

ActionController::Base.asset_host = Proc.new do |source, request|
if request.ssl?
“https://#{request.host_with_port}”
else
“http://asset#{source.hash % 4}.mydominname.com”
end
end

When I visit a page using HTTPS, some assets are pointing to a HTTPS
url, and others to a HTTP url. It turns out the contents of the layout
produces the HTTP urls, and the page action produces the HTTPS urls.

Perhaps the layout is being cached?? I need all assets pointing to
HTTPS urls when the page is requested using HTTPS, and likewise, I
need all assets pointing to HTTP urls when the page is requested using
HTTP.

Any thoughts as to why this is happening?
