Chapter 11, Problem 11.12HW
Program Plan Intro
IP addresses:
- The IP address denotes an unsigned integer that is 32-bit.
- The IP addresses is been stored by network programs in IP address structure.
- The addresses present in IP address structure are stored in network byte order.
- An unsigned 32-bit integer is transformed from host byte order to network byte order by “htonl” function.
- An unsigned 32-bit integer is transformed from network byte order host byte order by “ntohl” function.
- The IP address is presented to humans in a form known as “dotted-decimal” notation.
- Each byte is been represented by its corresponding decimal value and is separated by a period from other bytes.
Passing program arguments to server:
- The arguments for “GET” requests are passed in the URI.
- The character “?” separates filename from the arguments.
- The character “&” separates each argument.
- The arguments do not allow spaces in it.
Server passes arguments to child:
- The server calls “fork” to create a child process and calls “execve” to run program in child’s context once it receives a request.
- The child process sets CGI environment variable values.
- The “adder” program can reference it at run time using “getenv” function of linux.
Output is sent by child:
- The dynamic content of a CGI program is to be sent to standard output.
- A CGI program sends dynamic content to standard output.
- It uses “dup2” function for redirecting standard output to connected descriptor associated with client.
- The result written to standard output by CGI program, it goes directly to client.
