Maxim,
a while ago you replied to my question below.
Since yesterday I am trying to get hold of the proxy_host variable set
by the proxy module but without success, maybe you can help a little
with the code.
From the source I understood that the proxy module sets the proxy_host
var during NGINX startup. I guess, that happens on a per-location basis,
depending on encountering a proxy_pass directive.
Correct?
I should then be able to access the proxy_host variable during the
authentication phase (this is where my module sits).
Correct?
To get hold of it, I try to find the index of the proxy_host var in my
location config merge handler:
var.data = (unsigned char*)"proxy_host";
var.len = 10;
child->proxy_host_var_index = ngx_http_get_variable_index(cf, &var);
if (child->proxy_host_var_index == NGX_ERROR) { /* NOT FOUND, TRY
TO INHERIT */
child->proxy_host_var_index = parent->proxy_host_var_index;
return NGX_CONF_OK;
}
/* FOUND - This loca config has its own proxy_pass configuration */
In my handler, I then do this:
ngx_http_variable_value_t *value;
…
value = ngx_http_get_indexed_variable(r,
conf->proxy_host_var_index);
Does that make sense? I does not work for me, unfortunately.
(The log module does see the proxy_host variable and logs the expected
value for it.
