Hi,
The Content-Length http response header is blank. Anyone see that occur?
My controller is sending back xml from a Zaya graph. Everything works
fine on FF but it appears that IE wants the HTTP specification followed.
(Not so unreasonable.)
Controller and Ethertrace are below.
Thoughts much appreciated.
Thanks and regards,
Larry
My controller for the graph is:
def a_graph
# assumes param :set
response.headers["Cache-Control"] = "no-cache"
chart_id = params[:set]
stats = Statistics.new
stats.fetch_stats(chart_id.to_sym)
graph = Ziya::Charts::Column.new( nil, nil, chart_id )
graph.add( :axis_category_text, stats.series_labels )
graph.add( :series, "Series A", stats.series )
render :text => graph
end

Have you tried something like?: render :text => graph.to_s -- Michael Wang --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
