Proxy connection leaks when you open SSL WebSockets from a page in Internet Explorer 11 or Internet Explorer 10

Symptoms

When Internet Explorer 11 or Internet Explorer 10 establishes a new WebSocket connection to a WebSocket server over Secure Sockets Layer (SSL) through a proxy server, the number of active connections increases. After that connection is closed, the number of active connections does not decrease. Therefore, you can't establish a new connection to this WebSocket server after 12 connections because there is no available free connection.

Resolution

To fix this problem, install the most recent cumulative security update for Internet Explorer through Microsoft Update. Additionally, see the technical information about the most recent cumulative security update for Internet Explorer.

Note This update was first included in the MS16-001: Security update for Internet Explorer: January 12, 2016.

Status

Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the "Applies to" section.
