Our application (JavaScript) accesses the Content Server REST API using HTTPS. The CS is behind the firewall, we set up the OTAG as a proxy server. The application has no problem accessing CS directly, but it failes to use the proxy in Firefox. There is no errors/warning in OTAG log, neither in CS/IIS log. By tracing the browser response/request, we found there is a 500 error occured when the OTAG was handling the response from the CS for an OPTIONS request. Below is the content of error:

Below is the response from the CS, if I point the application directly to CS without OTAG.
