c++ - nginx / FastCGI application loads page multiple times per request -
i following this tutorial, , modified code , added counter it. page displays "hello world" , displays counter. now, weird thing is, code compiles fine, count goes 2 each time refresh page!
i'm spawning process this: spawnfcgi.exe -a 127.0.0.1 -p 8000 -f myapp.exe
everything loads ok, again, count jumps 0 2 4 etc. each time refresh page. if write line file, same line written multiple times, increasing each time load webpage. question is, intended effect of fastcgi application? or there kind of bug in code and/or fastcgi/nginx config?
main.cpp (hello world)
#include <iostream> #include "fcgio.h" using namespace std; int main(void) { int gcount = 0; // backup stdio streambufs streambuf * cin_streambuf = cin.rdbuf(); streambuf * cout_streambuf = cout.rdbuf(); streambuf * cerr_streambuf = cerr.rdbuf(); fcgx_request request; fcgx_init(); fcgx_initrequest(&request, 0, 0); while (fcgx_accept_r(&request) == 0) { fcgi_streambuf cin_fcgi_streambuf(request.in); fcgi_streambuf cout_fcgi_streambuf(request.out); fcgi_streambuf cerr_fcgi_streambuf(request.err); cin.rdbuf(&cin_fcgi_streambuf); cout.rdbuf(&cout_fcgi_streambuf); cerr.rdbuf(&cerr_fcgi_streambuf); cout << "content-type: text/html\r\n" << "\r\n" << "<html>\n" << " <head>\n" << " <title>hello, world!</title>\n" << " </head>\n" << " <body>\n" << " <h1>hello, world!</h1>\n" << gcount++ << " </body>\n" << "</html>\n"; // note: fcgi_streambuf destructor auto flush } // restore stdio streambufs cin.rdbuf(cin_streambuf); cout.rdbuf(cout_streambuf); cerr.rdbuf(cerr_streambuf); return 0; } nginx.conf
