>
> The Tomcat session state module does not commit session data to Geode prior
> to servlet output flushing to browser if commit valve is enabled. The commit
> valve delays the commit of session state until the of the request scope prior
> to closing and ending the current request with the browser. This can result
> in some data being sent to the browser asynchronously with the session state
> persistence. If the servlet or JSP invokes a flush on output stream, write or
> response either explicitly through the flush method or implicitly because of
> full buffers then the browser may receive data that instructs it to make
> another request. This subsequent request may receive the currently committed
> session state prior to the completion of the initial request.
