diagram of server phases

[Brian McQueen <mc...@gmail.com>]

I was surprised to discover that the translate_name handler goes
before the header_parser handler.  This made it clear to me that I'm
really not sure about what all of the standard hooks are or in what
order they are called.  I know the old camel book has a pretty
diagram, but its way out-of-date.

Maybe there is a way to get this by scanning through the headers or
through the source code?  How would I determine the order?

Does anyone know if this information is available?

Nick, will it be in your book?

Do you mean:

http://httpd.apache.org/docs/trunk/developer/request.html

?

For a comprehensive list of all available hooks, check out  
mod_example.c from trunk. It now has a handler for every hook in the  
server, whether it makes sense or not. If you build it with - 
DEXAMPLE_LOG_EACH=1 , every hook handler will write to the error log  
and you get a, very verbose, run-down of the calling order.

The header-parser is a general-purpose hook.  It comes after
translate_name and map_to_storage so that it'll run when
per-directory config (including applicable .htaccess) is
in effect.

If you want to scan headers earlier, ignore the name and use
a post_read_request hook.

There is a page somewhere in the developer docs @apache.org
that gives the order of hooks.  There's also an element of
legacy from Apache 1's less flexible architecture.

Chapter 6 deals with the request processing cycle and
metadata handling, and includes the order of standard
hooks with (brief) explanations and examples.
