Now Albert DeSimone is saying:
I assume "these virtual hosts" are "soft" (name-based) virtual hosts. I'm
sure no traces would show you otherwise. What I was saying was "have had"
a problem -- speculating that there was a time when Apache (for example)
supported name-based virtual hosts and ht://Dig was not sending the
Some of my confusion was brought on by the ht://Dig documentation --
specifically the description of the 'allow_virtual_host' configuration
If set to true, htdig will index virtual web sites as
expected. If false, all URL host names will be
normalized into whatever the DNS server claims the IP
address to map to. If this option is set to
false, there is no way to index either "soft" or "hard"
virtual web sites.
If my understanding is correct (and my tests weren't flawed),
then there should be no reference to "hard" in the last sentence --
only "soft" sites are affected by 'allow_virtual_hosts'.
