Review week thirteen lab assignment
The Apache HTTP server must be instructed to locate the CGI scripts.
Two pieces of information are needed to execute your CGI script.
1) A program in that directory to be used as a CGI script.
2) A link in an HTML page to your CGI scrip
Need to provide a URL that points to the CGI script.
http://cs.franklin.edu/~dandrear/itec400/CGI/sysInfo.cgi
Review week thirteen lab assignment
The CGI script itself simply produces output to stdout. The HTTP server captures that output and sends it to the Web browser. The format of the output must be in a form that the Web browser can understand (HTML).
The CGI script creates the HTML page every time it is run.
The data provided to the HTML page can change with each execution of the script.
Next Lab AssignmentCGI Script
Use declaration Format: use CGI <List of methods>
start_html displays the name of the script top left corner of browser
start_form returns a <form>tag with optional method, action, and form encoding that you specify
Submit button sends all of the form information to the CGI program specified by the ACTION attribute. Without the button the form will be useless since it will never reach the CGI script.
