the conversion procedure is simple: - find all things that look like options, ie calls to either `mkOption` or `lib.mkOption` that take an attrset. remember the attrset as the option - for all options, find a `description` attribute who's value is not a call to `mdDoc` or `lib.mdDoc` - textually convert the entire value of the attribute to MD with a few simple regexes (the set from mdize-module.sh) - if the change produced a change in the manual output, discard - if the change kept the manual unchanged, add some text to the description to make sure we've actually found an option. if the manual changes this time, keep the converted description this procedure converts 80% of nixos options to markdown. around 2000 options remain to be inspected, but most of those fail the "does not change the manual output check": currently the MD conversion process does not faithfully convert docbook tags like <code> and <package>, so any option using such tags will not be converted at all.

|
If "ip" is given, client IP based session affinity is
|
|
enabled. If "none" is given, session affinity is disabled.
|
|
|
|
Session affinity is enabled (by nghttpx) per-backend
|
|
pattern. If at least one backend has a non-"none" affinity,
|
|
then session affinity is enabled for all backend servers
|
|
sharing the same pattern.
|
|
|
|
It is advised to set affinity on all backends explicitly if
|
|
session affinity is desired. The session affinity may break if
|
|
one of the backend gets unreachable, or backend settings are
|
|
reloaded or replaced by API.

Name resolution of a backends host name is done at start up,

|
or configuration reload. If "dns" is true, name resolution
|
|
takes place dynamically.
|
|
|
|
This is useful if a backends address changes frequently. If
|
|
"dns" is true, name resolution of a backend's host name at
|
|
start up, or configuration reload is skipped.

If true, a backend match requires the frontend connection be
|
|
TLS encrypted. If it is not, nghttpx responds to the request
|
|
with a 308 status code and https URI the client should use
|
|
instead in the Location header.
|
|
|
|
The port number in the redirect URI is 443 by default and can
|
|
be changed using 'services.nghttpx.redirect-https-port'
|
|
option.
|
|
|
|
If at least one backend has "redirect-if-not-tls" set to true,
|
|
this feature is enabled for all backend servers with the same
|
|
pattern. It is advised to set "redirect-if-no-tls" parameter
|
|
to all backends explicitly if this feature is desired.
