sendRedirect() javadoc

[vani venkat]

hi
can some one explain meaning of

If the response has already been committed, this method throws an IllegalStateException. After using this method, the response should be considered to be committed and should not be written to.

it is given in javadoc of sendRedirect method.
does that mean, we should not call flush() on response once we call sendRedirect? or we should not even try to write into response?

Hi, Vani. Yes. If flush() is called the response is commited(closes the underlying stream).

thanks chinmaya for clarifying. i got a doubt by reading that "written to".
