What's causing “Session state has created a session id, but cannot save it because the response was already flushed by the application.”

Question

I\'m getting this fault intermittently.

I found this link which summarises fairly well what I was able to find on the Google: http://www.wacdesigns.com/2009/02/03/s

I believe the issue here may be exactly that you're doing something to cause page output during Page_Load, which, according to the ASP.NET Page Lifecycle Overview is long before the rendering stage.

Ensure that you never do anything that could trigger page output until after the PreRender stage.
