I have a sp2010 website where I am trying to use a network path for the images as I have a WebFarm which is loadBalanced using CISCO ACE appliance hardware (without IP Stickiness). The reason I am using a network shared folder is that at times the Chart does not show the PNG images. I am using UpdatePanel with Timer to update the chart every minute
The problem with displaying the PNG images in the Web Farm comes when I had initially the web.config setting as shown below.
<add key="ChartImageHandler" value="storage=file;timeout=10;dir=c:\TempImageFiles\;" />
So I used the network Shared path as per the article, where I have FULL Permissions on EVERYONE, NETWORK Service.
Below is my current setting for the Network shared folder path and I keep getting this error: Invalid temp directory in chart handler configuration
<add key="ChartImageHandler" value="storage=file;timeout=10;dir=\\servername\TempImageFiles\;" />
Can someone help.
