Subject HTTP Transaction State Diagram updated?
Date Tue, 26 Nov 2013 09:07:53 GMT
Hi,

I've found that the State transition in HTTP Transaction State
Diagram<http://trafficserver.readthedocs.org/en/latest/sdk/http-hooks-and-transactions.en.html>
may
be incorrect.

Per my http.* debug log,

> (http) [0] State Transition: STATE_UNDEFINED -> API_READ_REQUEST_HDR
> (http) [0] State Transition: API_READ_REQUEST_HDR -> HTTP_API_PRE_REMAP
> (http) [0] State Transition: HTTP_API_PRE_REMAP -> HTTP_REMAP_REQUEST
> (http) [0] State Transition: HTTP_REMAP_REQUEST -> HTTP_API_POST_REMAP
>
> *(http) [0] State Transition: HTTP_API_POST_REMAP -> CACHE_LOOKUP(http)
> [0] State Transition: CACHE_LOOKUP -> DNS_LOOKUP*
> (http) [0] State Transition: DNS_LOOKUP -> API_OS_DNS

CACHE_LOOKUP is just after POST_REMAP and is ahead of DNS_LOOKUP.

But in the State Diagram, CACHE_LOOKUP is after OS_DNS_HOOK.

I'm using ats-4.0.1, it would be great if some body can correct the
diagram.  :)
Many Thanks!

-Ethan
