Advanced. Trapped in architecture.

Hi there, I have a serious problem in my programming architecture. The architecture looks like fusebox (those of you familar with CF might now this a.) The point is, that I am sending html code at the beginning. Body tag and so on. Now there is the content. And inide this content there might be anywhere an if statement. This if statement should be able to redirect to another Page. I tryed this with the header location statement. Which workes fine as long as output buffer is on. Having output buffer on leads to extreme performance loss. During db access you see a blank screen for seconds. Here is the question: How do I redirect to another page in this case. JS might be a solution. But I really would like to avoid to be dependend on the activation of JS in such a elementery decision. So... how do you guys redirect to other pages? Might be a quick run for you guys, but I am totally stuck here. Thanx for any help Cheers Andy
