hi,
i am creating an simple http server ie it serves only static pages .
u can compile the code then use ur browser if it is IE then the it
shows the page but the http header is also shown
HTTP/1.0 200 OK Content-Type: text/html
nweb Web Server Sorry:
but if the browser is mozilla/Firefox it shows the recieved data as an
application and tells me to save it.
also i want that the program should continiously listen on the port and
send data to more than one client
also is it possible to invoke a thread that calls a function with
arguments
