Most browsers can show the HTTP-Header.
E.g. in firefox -> developer tools -> network -> just click on any
object and it will show headers (and much more)
Or you can place a simple script in httpd that dumps the header.
In PHP for example you can do: print_r($_SERVER);
What I do is placing a simple C program in /cgi-bin:
#include <stdio.h>
int
main(int argc, char *argv[])
{
extern char **environ;
printf("Content-Type: text/plain\n\n");
for (int i = 0; environ[i] != NULL; i++) {
printf("%s\n", environ[i]);
}
}
