Does there exist an english introduction to NginX config 'programming'?
I have found various example configurations, both simplistic and 'full
I have found the list of modules on the wiki, and the command-centric
documentation they supply. (Though I wish even this were more in-
depth. For example, what is the regex syntax allowed for the rewrite
command? PCRE? Posix classes? Lookaheads/lookbehinds?)
What I'm missing is an overview of how configurations really work.
With the ability to set variables, scoping, break directives and
rewrite commands like last/break/redirect/permanent, it's more like a
programming language than a set of parameters. Various questions this
has raised in my mind regarding the sort of information I'm looking for:
What is the 'flow' of execution?
When you 'break', what scope/context are you stopping the directives in?
When all is said and done, what is being returned?
Can I chain multiple rewrites? Does a rewrite affect all kinds of
later matches (e.g. 'if' or 'location')?
While answers to the above specific questions would almost certainly
help me string a few islands of knowledge together, I'm hoping someone
knows of a guide already written. Something that starts at NginX
Config Theory 101 (not super-simple examples, but instead something
like stepping through the procedure of matching a request against a
config file from start to finish) and then covers things like Virtual
Hosts and Virtual Directories and so on.
Any chance it exists?
