Client-Side Technologies                                              2-5


  Any      client-side technology is allowed
    ›Client-side scripting such as JavaScript, Jscript and VBScript
    ›Client-side executables such as ActiveX and Java applets
    ›Cascading Style Sheets
  Also    works with Java server-side constructs (JSPs, servlets, tag
   libraries) but not other server-side technologies


  Note: While other server technologies cannot be included in
  ColdFusion pages, they can be accessed by web services.

Unit Summary                                              2-11

   When a static page is requested, the web server sends the
    page to the browser in the form of HTML. The browser then
    interprets the HTML and displays the page.
   Dynamic pages let you create dynamic content that updates
    itself based upon time or user.
   When a dynamic ColdFusion page is requested, the web
    server passes the page to the ColdFusion MX server that
    processes the ColdFusion tags and sends the results back to
    the web server as HTML. The web server combines that
    output with the HTML on the original page and returns it to the
    browser.
   ColdFusion is a server-side technology that lets you create
    dynamic web pages and complete web applications quickly
    and easily.
Unit Summary (continued)                         2-11

   CFML is a server-side markup language that is similar to
    HTML.
   ColdFusion MX components include the ColdFusion MX
    server, Dreamweaver MX, and CFML.
   ColdFusion MX works with a broad range of web servers.
   For development, all components can reside on the same
    server. For production, however, you will want a more robust
    configuration.
