Output HTML Compression

Hi, Any tips on how to speed-up dynamic page loads by either lessening the HTML file sent or compressing it? I found two ways but don't exactly know how to do it. 1. Enable output buffering with compression. This seems to be only available on php4.04. Is there a way to do this with php4.01? 2. Remove extraneous whitespaces. I normally program with heavy use of indention, especially in table outputs, to make code more readable. But the html files sent out also have these indentations and whitespaces. Is there a code that can clean these out? Thanks, Floyd
