20 Chapter 3. Conﬁguration

These three tunables depend on each other, and the strip_host_tail tunable is only used

if host based virtual serving is enabled. Otherwise, it is ignored.

3.8.1. virtual_server

If the value is set to 0, virtual hosting is disabled:

http://www.example.com/a.html => $DOCROOT/a.html

If the value is set to 1, host-based virtual hosting is enabled:

http://www.some.site.com/a.html => $DOCROOT/some.site.com/a.html

Note

TUX strips off the www. preﬁx variants and transforms the hostname to lowercase.

If the value is set to 2, IP-based virtual hosting is enabled:

http://www.some.site.com/a.html => $DOCROOT/1.2.3.4/a.html

If the value is set to 3, a mixture of host-based and IP-based virtual hosting is enabled:

http://www.some.site.com/a.html => docroot/1.2.3.4/some.site.com/a.html

3.8.2. mass_hosting_hash

The mass_hosting_hash tunable modiﬁes the hostname mapping to be more effective for a

large number of hosts.

If the value is set to 0, mass_hosting_hash is disabled.

If the value is set to 1:

http://www.some.site.com/a.html => docroot/s/some.site.com/a.html

If the value is set to 2:

http://www.some.site.com/a.html => docroot/s/so/some.site.com/a.html

If the value is set to 3:

http://www.some.site.com/a.html => docroot/s/so/som/some.site.com/a.html

3.8.3. string_host_tail

The strip_host_tail tunable strips off hostname components, starting at the end of the

hostname.

If the value is set to 0, this tunable is disabled.

If the value is set to 1:

1 2 ... 15 16 17 18 19 20 21 22 23 24 25 26 27 28
