Good news if your site is hosted with Aspire Web you are already protected from the latest vulnerability, httpoxy CVE-2016-5387.
If your interested in more technical details see: https://httpoxy.org/
As all our current customers are running on Windows using IIS and the FASTCGI interface for running additional scripting languages (PHP/NodeJS) our services are protected!
Microsoft have released a KB explaining how this affects IIS and how this is only an issue if you are running the old CGI interface which we have never used, see more here: https://support.microsoft.com/en-us/kb/3179800
