I want to write a module to redirect a request to a specific server by
uri. when received a request, I need to calculate the secific server’s
ip with the number in the uri.
I have tried the function of ngx_http_internal_redirect(), but it seems
useless to redirect a request to another server. Is there any function
can do this?
My purpose is similar to the rewrite module with the directive of
"permanent " , but I can’t quite understand the rewrite module,
especially the function of ngx_http_rewrite_handler(). Can I just modify
the some members in the struct of ngx_http_request_t?
thank you fo any help.
