        It is not broken, but surelly misleading. I had a bug with a
proprietary apache 1.3 module, which was used to serve dynamic content
for a commercial CMS. This module started to send a "Content-Lenght: 0"
header, when the content was delivered from NFS.
        This bug caused mod_proxy (from Apache 1.3) and some versions of IE not
to be able to retrieve the page successfully (and show a blank page,
instead).

        Apache's implementation of SSI (mod_include) simply removes this
header, when sending dynamic content ("size calculation is costly on
dynamic pages", they say).
