You can iterate over locations in a server block using "locations" queue in
ngx_http_core_loc_conf_t. You need to use the location configuration at
the server level to access the queue. Referencing the example from your last
email, it should be something like this:
clcf = cscfp[s]->ctx->loc_conf[ngx_http_core_module.ctx_index];
/* iterate over clcf->locations */
See ngx_http_core_location() as an example of how this queue is filled and
ngx_http_merge_locations() as an example of how to iterate over it.

Accessing proxy module to iterate over locations does not sound like the
right decision.
