How to pass data from server (CGI script) to client (html page)

Shell Programming and Scripting

Hi
I know how to pass data from client side (html file) to server using CGI script (POST method).
I also know how to re-create the html page from server side after receiving the data (using printf).
However I want to write static pages on client side (only the structure), and only to pass information (data) from server to client (which data to display in the form created statically).

  1. How do I pass the data from the server side?
  2. How does the client side receive the data from the server?
    Thank you
