If you are using CFCONTENT with images or PDFs you will run into serious troubles with ColdFusion 10 Updater 14. These updater contains an upgrade of the IIS connector and will break your websites. This is known to be an issue with ColdFusion 11 and ColdFusion 10. The bug has been logged with Adobe as coldfusion 10 update 14. failed to load pdf document, but the issue goes far beyond PDFs.
Symptoms:
- An URL use CFCONTENT tag to output a PDF or an image to the browser. If you have URL parameters attached to this URL it will fail to download.
- Wireshark traces show that no binary data is send to the web browser. You only see a GET and some headers, but no content.
