Varnish1.1.2 returns 200OK,but no content

[Christophe Husson]

I've a similar problem with http 1.0 protocol on dynamic objects like
php generated data.

Some log from varnishlog:

15 TxRequest    b GET
15 TxURL        b /bug.php
15 TxProtocol   b HTTP/1.0
...
15 RxProtocol   b HTTP/1.1

13 VCL_return   c pass
13 Length       c 0
13 VCL_call     c deliver

The web server (Apache 2) don't send content-length or transfer encoding
chuncked header.
Varnish calculate the objet length only when the get query use http 1.1
protocol (/bin/varnish/cache_fetch.c line 346) or if the server reply
whith a content-length or transfert encoding chunk header.

Can this be fixed ?
Thanks
