Sure! And module A can also create module B's ctx for B to "fool" B ;)
ngx_http_get_module_ctx just reads an item from the r->ctx array using
the module index. No magic here :)

Just as a side note, I've designed a way for a module to detect
existence of another module at runtime, so as to implement "optional
dependency" mechanism for nginx modules. It's all about mudding
ngx_modules and looking for special directive name strings in each
module struct's commands array :)
