It sends the +expected requests to the web server over a network socket connection and +displays the results as text rather than graphically displaying the results. In +the code you will have to change the two lines as below to match your web +server or nweb server. + +/* YOU WILL HAVE TO CHANGE THESE TWO LINES TO MATCH YOUR CONFIG / #define PORT + * 8181 / +Port number as an integer - web server default is 80 / #define IP_ADDRESS +"192.168.0.8" / IP Address as a string */ + +The default is to request the /index.html from the web server. If you want to +request another file then change the GET line as below: + +char *command = "GET /index.html HTTP/1.0 \r\n\r\n" ; + +To, for example: + +char *command = "GET /nigel.jpg HTTP/1.0 \r\n\r\n" ; + +Then compile the program with: cc client.c -o client + +I save the output in to a file as putting a non-test file like .jpg to the +terminal screen can cause chaos: client >output + +Then edit the output file: vi output + +In real life, the interaction of web browser and web server can be much more complex. + + 1.
