Hello everyone,

Recently for some of our needs on Nginx, I am working to develop a new module on Nginx. So I have started to develop a test and basic module. My intention is to call a function before selecting one servers in upstream section. For this, I set NGX_STREAM_MODULE type. when running the nginx with new option "stream_test" in upstream configuration, I get below error :
ERROR: nginx: [emerg] "stream_test" directive is not allowed here in xxxxxx

I will appreciate if somebody assist me on this.Thanks

Following is the source code of test module
