Hi,
2. Any good advice on how I should do it? I was thinking on adding the
validation somewhere in ngx_http_upstream_test_next (ngx_http_upstream.c),
something like:
if (r->method == NGX_HTTP_POST) {
return NGX_DECLINED;
}
Keep in mind that you should decline sending request to another backend,
only if you already sent it upstream. There is a bunch of errors (bad
gateway, connection timeout, etc) which could lead to the code path in
question, for which you should still send request to another backend.
