Dynamic automatic answers system #1080

Closed Wonshtrum closed 6 months ago

Wonshtrum commented 7 months ago

Make all automatic answers configurable. The goal is to be able to provide an HTML-like file for each automatic answer generated by Sozu. The format allows some templating to generate dynamic responses. The format is parsed from Http/1.1 to our Kawa intermediate format only once and at the start of a worker. Parsing resolves all templating variables and generates a trivial in-place replacement strategy. Filling a template should be as performant as possible.

TODO:

[x] add status line to elements that can be passed to a Template
[x] list other elements that can be meaningful for each HTTP error kind

It would be meaningfull to add a CLUSTER_ID replaceable variable in the template, for errors 502, 503, 504 and 507.

Keksoj commented 6 months ago

providing cluster id as CLUSTER_ID where possible would be very nice too. So, to sum up:

CLUSTER_ID
STATUS_LINE
DETAILS
SOZU_ID (request id)

wait, I messed up something when rebasing main
