socket_problem

How can I make this server to send any type of file format apart from html?

sprintf(header, "%s 200 ok\r\nContent_type :text\html\r\n\r\n", prt);

Does this mean that I woulkd have to edit this line anytime I need to include other file types?
How do I get the server to detect the file being requested automatically?
And thanks for noticing some of those minor errors.
Hope this is better:
