Hi,
I have a handler, that serve dynamic pages or static ones. If the handler gets
a HEAD request, it answers with

it is desired - you no longer need to set the Content-Length header for
requests in Apache 2.0.
It's somewhat documented:
http://perl.apache.org/docs/2.0/user/handlers/http.html#Handling_HEAD_Requests
basically, any C-L header you set in the content-generation phase of the
request has the potential to be incorrect, since any filter can come along
and alter the content. so, what apache does is it runs the new
content-length filter, which will decide whether a C-L header is required
and take appropriate steps. for instance, apache will abandon the C-L
header if it decides it can use a chunked transfer encoding instead.
Geoff, feel free to improve that section to be more complete. Thanks.
