Hi all,

Just hoping somone could point in the right direction. Have just started
learning to program sockets and have programmed both a client and server to
send and recieve messages, but now need to develop a web server to deliver a
web page. Obviously the server program would not have to change much, but to
send a file rather than a message, and I am using a browser as the client.
Any suggestions to what I should be looking at to enable the ability to grab
the file and deliver it??

TIA

Hi,
You can use a while() loop to send a file - line by line. Something like

while(fgets(line,1024,fp) != NULL)
{
write(sockfd,line,strlen(line));
// anything else you want to do
}

I coded one such web server-client application in PERL. Hope the same works 
in C.

regards,
GVK

By definition, a Web server implements the server side of HTTP, which is
specified by RFC ("Request for Comments") 2616, which you can read here:

http://www.w3.org/Protocols/rfc2616/rfc2616.html

There's a simple example of a Web server here:

(Look in the examples for Chap. 8)

Thanks all, what I really needed was to use:

file = fopen("homepage.html","r");
fread((void*)buffer,1,1023,file);
write(CS_sock,buffer,strlen(buffer));

(with other error code).
