[Bug 62184] Documentation: UNIQUE_ID length change from 24 to 27 characters
https://bz.apache.org/bugzilla/show_bug.cgi?id=62184

--- Comment #2 from Christophe JAILLET <christophe.jaillet@wanadoo.fr> ---
There is much more to change in the mod_unique_id documentation.

As noted in a comment in r1501827:

* Note: previous implementations used 32-bits of IP address plus pid
* in place of the PRNG output in the "root" field. This was
* insufficient for IPv6-only hosts, required working DNS to determine
* a unique IP address (fragile), and needed a [0, 1) second sleep
* call at startup to avoid pid reuse. Use of the PRNG avoids all
* these issues.
