When the logger is used from any code running from the W3WP.exe there is no issue. But when the logger is used from code running in the full trust proxy (SPUCWorkerProcessProxy.exe) we get a System.Net.WebPermission denied exception.
Both process are running with the same user account. So it's not clear to me why the Worker Process Proxy cannot send log over http while the w3wp is able to do so.
Any clue how to troubleshoot this?
