Custom Coldfusion 404 error template per website, IIS7
I have a Windows 2008 server running IIS 7 & Coldfusion 9.0.2 multi instance. I have 3 separate Coldfusion instances, one website per instance. I created unique 404 error pages (404error.cfm) for each website to include that website's header/footer and put the files in their website's root directory. The IIS error page configuration does not appear to be working as I thought it should.
I go into IIS, siteA, error pages, open Edit Custom Error Page for the 404 error, check off Execute a URL on this site. For the URL I enter /404error.cfm. In the featured Settings it doesn't matter which of the 3 items I select. What happens is it runs 404error.cfm at the COLDFUSION ROOT level (JRun4\servers\cfusion\cfusion-ear\cfusion-war\404error.cfm) (I put the file there). Not good because that is not site specific. I modified the CF rootdir 404error.cfm to run the 404error.cfm at the website's root level but it knows nothing about application scope variables nor session scope variables.
How can I get IIS/CF to run 404error.cfm in the website's root directory directly without going thru that CFroot 404error.cfm file?
