West Wind Web Connection
(& Visual WebBuilder)
Web Connection is a complete Web application framework for developing and delivering scalable e-business solutions. It is a proven development platform for integrating browser, server and database
technologies into Web applications for Visual Studio and especially Visual FoxPro developers. The framework features tools to build HTML based applications as well as rich distributed applications with clients in the Visual FoxPro or
browser environment focusing on the latest in XML technology.
Connect Visual FoxPro to the World Wide Web with West Wind Web Connection and take full advantage of Visual FoxPro's powerful data access and programmability for creating dynamically generated Web
content. Web Connection provides a scalable Web platform for building fast, powerful and flexible applications with ease. Take your pick between code based HTML creation or FoxPro based HTML scripting, dynamic form rendering or PDF Report
generation, or powerful features for generating XML to create your Web output. The supplied classes and tools greatly simplify receiving Web server requests, using the provided information and generating the final dynamic HTML and other
data content like XML or raw data to return to the client. In addition Web Connection includes powerful client side tools for accessing Web and Internet content from Visual FoxPro to build rich distributed applications utilizing XML and
What is Web Connection?
Take advantage of Web Connection's cutting edge technology that leverages Microsoft Internet Information Server, ISAPI, COM, Windows DNA and Visual FoxPro for building
high performance Web backends that can handle large scale production loads. Web Connection has been rigorously tested and deployed in a live environment on one of the busiest commercial online stores at the time on the Web running as many
as 1.5 million Web Connection Server hits per day maxing out 3 full T1 lines. Web Connection has been tested in excess of 3 million backend hits a day on a single dual processor server during load testing. Although Web Connection works
best with Microsoft Internet Information Server it can run on any ISAPI or CGI compliant Web server.
And Web Connection is ready for the next wave, too: The Enterprise Edition features a COM object pool manager that allows building VFP servers that can be scaled and at the same time interface with
other Microsoft Internet Technologies like COM+. And unlike other tools from Microsoft, Web Connection makes it easy to develop COM applications. Build and debug the application interactively in the VFP IDE, then simply switch into
COM operation mode from a Web link and take advantage of COM performance, scalability and administration without the development hassles of a pure COM environment - get all the benefits of COM without the development and administration
pain. Compiled servers can run either as COM objects or as standalones for testing and debugging.
And that's not all. Web Connection even provides the tools to let you build powerful distributed Web applications that take advantage of XML, client side HTTP messaging, and data transformations
for applications that rely on content other than HTML. Use a VFP backend (or a VFP->SQL Server/Oracle backend) to serve as an XML data server providing XML input and output
from VFP cursors, SQL backends and stored procedures and even VFP and COM objects. Or use Web Connection's powerful Web Services feature that allow you to build SOAP based Web Services that can be called from any SOAP compliant client
application. Call these XML server applications with wrapper classes from VFP clients or use plain XML messages to call it directly from browser, java or any client on other platforms.
Get your business data online and have your VFP applications share data over the Web today without having to rely on clumsy HTML interfaces! Use VFP as a client and/or data server. The
opportunities are endless. Check out our distributed Web demos for ideas on how to use this powerful technology. (These demos require IE5 and VFP6 installed on the client).
Web Connection includes a 2 meg help file for online documentation with a rich User Guide that includes a number of Step By Step guides to
take you through various tasks. A complete class reference is also provided with rich examples. "The best documentation in the business", rave some of our customers. There are also over 30 sample requests that demonstrate the features of Web Connection and several demo applications that put the pieces together for a full fledged application. The West Wind Message Board forum
software is provided with full source code, including the offline reader which demonstrates using a VFP client side application sharing data with an online Web application.
Web Connection is a developer tool and ships with full source code for the object oriented Web framework and all of the support tools and sample. This is a fully open architecture that you as the
developer have control over - no hidden away black box code here! Use the source to customize, learn and protect your investment into the future.
But don't take our word for it: You can download a fully functional shareware version to try for yourself. You may also want to

Web Connection consists of two major pieces of software that make up the overall product. A small C++ based connector application (ISAPI dll or CGI exe) that implements the communication interface
between the Web Server and your Visual FoxPro application, and an extensive framework of Visual FoxPro classes that makes it easy to build application specific Web code. The Visual FoxPro framework is open and is shipped with full source
code with any registered version of the product.
The Visual FoxPro framework consists of classes that manage communication with the Web connector ISAPI extension. They handle server management and administration, retrieving server and browser
form variables from the server making them easily available to your code and providing a powerful set HTML classes and support tools that make short work of interactively building the HTML required to display your application on the Web.
Web Connection provides access to all advanced HTTP based features including built in support for frame-management and displaying HTML script pages containing FoxPro code and expressions from disk. Many advanced features like HTTP
Authentication, HTTP Cookies, Sessions, custom HTTP headers, request logging, remote administration and configuration and server load balancing are built into the product. And you can use Web Connection with tools like FrontPage or Visual
InterDev to design your pages and still use Web Connection to run your FoxPro code inside of them and even call these pages directly from your code!
The framework is a utility framework rather than an application framework such as FoxExpress, MaxFrame, Mere Mortals or the like. Rather you can use existing frameworks and their business classes
with Web Connection. Web Connection provides the Web server plumbing and interface to your application, but not the business object framework. The idea is that this tool should not interfere with the way you build applications today - you
use what you already know and add Web functionality to it. Keep in mind though, that Web Connection will not take an existing application and magically run it as a Web application. The user interface will need to change or at the very
least have to be tweaked to be workable as a Web interface. You'll use Web Connection as the front end and build transaction based logic using either straight procedural FoxPro code, or business objects of your own.
Web Connection also provides advanced tools for building distributed Web applications that use VFP or XML clients to access data and logic on the Web server. With Web Connection you can run SQL
queries and execute COM objects over the Web or use plain manual Web requests to provide data to client applications. Web Connection provides the client side HTTP tools as well as high level XML conversion tools that make XML integration a
snap. The Web isn't all about HTML and these data messaging features let you build powerful distributed applications that aren't limited by HTML output.
There's ample of documentation in our help file and over 30 short examples and several sample applets that demonstrate a wide variety of the features available in Web Connection. All samples come
with source code for you to check out and plug into your own code.
There are also several small sample applications that show how to put individual features together into a working application. Among them is the the West Wind Message Board application used on the
West Wind site, which ships with full source code and demonstrates a full blown Web application that provides an HTML interface as well as using a distributed architecture to share data over the Web using the Offline reader application.
Web Connection has been field tested on a number of high volume sites. Web Connection has been run at over 1.5 million+ requests per day at www.surplusauction.com and not even close to maxing out.
This busy site is (was – surplus merged with onsale.com) one of the top commercial sites on the Internet.
…and what it isn't
Web Connection makes it easy to build Web applications, but it will not take an existing application and run it on the Web as is. Work is required to convert the interface to an HTML based
design and if your application mixes interface and database logic tightly, existing code might not be easily integrated into your new Web application. On the other hand if your business logic is separated clearly from the interface then
reusing business rules and other rule based classes or procedures will be easily integrated into your Web applications. Keep in mind you will have access to almost all of Visual FoxPro's wonderfully powerful features with limitations on
VFP's GUI features!
Web applications are server based and respond to requests made from a Web page. As such they are not event driven or even really interactive. Rather a request made on your server is typically
treated as an entire transaction in and of itself and must be fully self-contained. In the stateless world of the Web transaction based programming is the norm and it's rather different than typical Visual FoxPro based Windows application
programming. In some ways it's more work to build the interface, in others it's strangely simple to build straight line processing code that grinds through data and spits out the results or a populated input form without having to worry
about all the GUI logic (80% of most apps is spent on GUI issues?).
Another option for existing standalone applications is to build a distributed application that use the Web as a data transfer mechanism. If you go this route your UI code can potentially be reused
using data pulled down from the server using tools in the wwIPStuff library. See the Online Distributed Application Demo (requires VFP6!) for an idea of what you can do.
If you're new to the Web take a deep breath and read on - there's lots of info in this document that will clarify the way the Web works. Web Connection makes it easy to leverage your FoxPro skills.
Once you understand the basic flow of information over the Web things will fall into place and allow you to be productive very quickly. You can crank out quality high performance applications without having to learn all of the Web
technology up front and you'll learn about Web technology as you use Web Connection to build applications.
