Buffering and redirecting

hi, In ASP we have something called response.buffer which doesnot write/send anything to the client until an explicit flush or normal processing ends or an response.redirect is coded. i would like to know the equivalent in php. i have to process something and then on successful completion have to redirect it to some other page. (more details like update a table from the details obtained from the previous html page.) how do i do it?? if i use a header(location ...) it says some output is already sent to the client.. is there any way to curtail responses from being sent to the client???? ______________________________________________________ 123India.com - India's Premier Portal Get your Free Email Account at http://www.123india.com
