Not purely a Flex question, but came up as a result of building a Flex reporting component... Using IE 6.0.2... When I download http://myserver.com/index.htm with a SWF embedded in the HTML Flash works fine and runs the embedded SWF in the browser. When I download http://myserver/filename.swf Flash also works fine and runs the SWF in the browser. But when I download http://myserver/reportwrapper.cfm?rpt=1 which contains <cfreport template="#url.rpt#.cfr" format="flashpaper"> IE prompts me with a popup dialog box that says: File name: reportwrapper.cfm File type: Shockwave Flash Object From: myserver.com Would you like to open it or save it to your computer? Why is it that filename.swf will trigger the Flash browser plugin but a CFM that has a Shockwave Flash Object mime type won't? Is IE confused because the file ext doesn't match the mime type? Is there a fix or workaround for this? Something i can do in Coldfusion to re-set the mime type to something else, or set content headers first, or something? Doesn't seem to do this in IE 7, but I have some IE 6 browsers in my organization and need to figure out a way to handle this. Thanks Darren
