C1 Community

Hi,

I have installed our Web App which uses the C1 WebChart onto a new server (Win2008 x64, IIS 7) but everytime I go to a page which should render an chart I get the following error: The file '/c1chartimage.aspx' does not exist.  This error is actually being picked up by the Application_Error funciton in Global.asax and writing it to a log file, the actual page just shows an 'X' (broken image link) icon.  We have test installed it on an old Win2003 server and it worked fine (although this had a previous working version on it also rather than a completely blank machine).

The version of C1WebChart we are using is 2.0.20071.17032 and we are using the ImageRenderMethod=HttpRequest and Imagetransfermethod=File (and also tested Session but same result), and I have checked the permissions on the C1WebChartTemp directory (where .png files of the charts are being created successfully).

If anyone has any ideas why we would be seeing this error it would be most appriciated,

Steve

After some searching on Google I discovered that IIS7 has a new 'request pipeline' which can be set in the Application Pool. 

If it is set to Integrated IIS7 will ignore the HttpHandler section of the web.config - but simply setting the App Pool to run in Classic mode solves this problem.
