How to write a channel.html file in Rails (for Facebook)

Question

According to the FB SDK I must include a channel file with the appropriate headers.

Being a major NOOB and a Rails not PHP developer I have no idea how to do this.

Inside your controller:

cache_expire = 1.year
response.headers["Pragma"] = "public"
response.headers["Cache-Control"] = "max-age=#{cache_expire.to_i}"
response.headers["Expires"] = (Time.now + cache_expire).strftime("%d %m %Y %H:%I:%S %Z")
render :layout => false, :inline => ""
