Your helper always exits after the first response.

You must continue reading until EOF.

Example template for a Squid helper: (all kinds)

int main(int argc, char **argv)
{
char buff[MAX_BUFF];
setbuf(stdout, NULL);

// Initialization

while(fgets(buff, MAX_BUFF, stdin) != NULL) {
// Process request in buff and return response to stdout.
}

return 0;
}

Henrik
