SYMPTOMS

When a Microsoft .NET Framework 2.0 application calls the HttpListenerResponse.SetCookie method, multiple cookies may be merged under one Set-Cookie header in the HTTP response. This problem occurs when you use HttpOnly cookies or non-RFC 2965 cookies.

Note A managed client merges the multiple cookies under one Set-Cookie header before the managed client presents the stream to the client application. Unmanaged client applications and non-RFC 2965 client applications receive multiple Set-Cookie headers that are written by the server.

A supported hotfix is now available from Microsoft. However, it is intended to correct only the problem that is described in this article.
