    • Interacting with VFP The Basics Standard Objects Generating HTML Rendering Forms & Data Binding Processing Form Input mmm Cookies!
    • The Basics Web Connection & AFP are ISAPI Extensions WC & AFP files use <% and %> as script delimiters VFP Code can fall anywhere within a web page between delimiters Classic ASP is very similar except code is VBScript/Jscript that gets to VFP via COM. ASP.NET, PHP and other server platforms with COM support can also talk to VFP
    • VFP Hosts TekQuest.com Shelbynet.net DNGSolutions.com
    • Basic Sample Pages Hello World… Server Info
    • Standard Objects Request – input  QueryString  Form  ServerVariables Response – output  Write  Redirect  Cookies  Status Server – duh  UrlEncode  UrlDecode  HtmlEncode
