How to disable RC4 cipher on Azure Web Roles

Question

I have a web application that is hosted on Microsoft Azure Web-Role. How can I disable RC4 cipher?

Answer 1

Last week there was a blog post update which will disable RC4 cypher by default on cloud services. https://azure.microsoft.com/en-us/blog/azure-services-ssl-tls-cipher-suite-update-and-removal-of-rc4/

This update should be rolling out this month and if the operating system version is configured as automatic it will be automatically installed on the cloud service(see image below)

Next guest OS: WA-GUEST-OS-4.31_201604-01
Release date: May 2 2016
