    CF10 and IIS 7.5 - cfheader in 404 custom error handler not working correctly

    redtopia-dev

      I'm getting some really weird behavior when handling 404 errors after updating to CF10 using IIS 7.5 on a Win2k8 R2 x64. IIS randomly delivers only a portion of the HTML page when I set the 404 status code using <cfheader statuscode="404" statustext="Not Found"> inside my 404 handler page (/404.cfm).

       

      In IIS, I specify "/404.cfm" (execute a URL) as my custom error handler page for 404 errors, which in turn calls <cfheader statuscode="400" statustext="Not Found">. This has worked really well up through CF9. However, after updating to CF10, something is broken.

       

      When I remove the code: <cfheader statuscode="404" statustext="Not Found"> from my 404.cfm page, the problem goes away, but so does the 404 status code, which means that search engines will see this as a legitimate document. The question is, how can I return both the content of my 404.cfm page (it simply suggests other pages that the user might be looking for) AND the 404 not found status code?

       

      Any ideas?
