What browsers did you test ? > But wouldn't it be nice to have some mod_deflate option where you could specify that >mod_deflate should flush and send the currently compressed output every time it had >received a certain amount of input or every time it had generated a certain amount of >output. It's complicates things. Besides Apache never flushes output on timeout or amount of content - it flushes only if you ask it. > We are, for instance, using a template module to generate the output.

You can set $|=1 as Eagle book says: This method [r->flush()] is also called automatically after each print() if the Perl global variable $| is nonzero. Igor Sysoev
