Thx so far.
If I use

 httpd_accel_uses_host_header on

and put my domains in the hosts file, what do I then need the directive

 httpd_accel_host your.primary.domain

for? Since the entries in the hosts file are used (due to the first
directive), it is possible to use
a complete different server than given by ' httpd_accel_host', isn't it?
(Simply by the entries in the
hosts file)

And one more question:
Using

httpd_accel_uses_host_header off
httpd_accel_host your.primary.domain
redirect_rewrites_host_header on

shouldn't now the client requests go to server your.primary.domain, using different host
headers in these request, so that still virtual webservers could be used (if the webserver is configured to use the host-headers)?
Or is 'redirect_rewrites_host_header on' only used if I have a dedicated redirect script?

Sorry for all these questions, but I still do not understand this stuff completely.
