Software FX Posted September 15, 1999 Report Share Posted September 15, 1999 ChartFX IE 4 supports "on the fly" image generation, using this approach no files are generated so the server component is cluster-friendly. The only drawback using this approach is that you will not be able to generate image maps. Code in your page <IMG SRC="ChartImage.asp" WIDTH=500 HEIGHT=350> ChartImage.asp Source code <!-- #include virtual="/Include/CfxIE4B.inc" --><% ' Please note the way this ASP is coded to avoid any newline or other characters ' to be sent to the client (all the code is SERVER side code) Set chart = Server.CreateObject("ChartFX.WebServer4B") ' Add your code here to customize the chart ' Note the use of GetHtmlData instead of GetHtmlTag chart.GetHtmlData 500,350,"Image" %> Regards, Juan Cegarra Software FX, Inc. juanc@softwarefx.com -----Original Message----- From: Scott Deitz [ mailto:sdeitz@nordby.com] Posted At: Wednesday, September 15, 1999 6:22 PM Posted To: Server Conversation: temp files on clustered web servers Subject: temp files on clustered web servers Another question - we're actually using CfxIE4 beta... We have several web servers clustered using Convoy Cluster/WLBS. There have been some problems with broken image tags every so often while hitting the cluster web address. This doesn't happen when you hit the web server by IP address, bypassing the clustering software. What seems to be happening is that CfxIE creates the image file in the Cfx temp directory, then the user is sometimes moved to a different web server in the cluster before the image is displayed resulting in a broken image link. I'm not sure why this happens as this is one ASP page creating and displaying the image... Are there any strategies to deploy CfxIE on clustered web servers? Thaks for any advice...
