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

My guess is that graph.size doesn't return a value or returns an "empty" one.
Have you tried something like?:
render :text => graph.to_s
