-----------------------------------
Dear Paul
I am not confused with the shifting to another thread when executing Response.sendRedirect; the main issue is that before executing response.sendredirect("index.html"); in Method3 (); all the statements in Method1() after the call of Method2() should be executed (Stm1 and others if available).
Thanks a lot for usual support
Best Regards
