The following is a list of the Barracuda examples. The examples share a common build structure which is explained in Introduction to the Barracuda Examples.
You may get strange results or "page not found" when using the same browser for the various examples. The browser gets confused with the cache handling when switching from one demo server to another. The browser believes it is using the same server since the address is the same; however, another demo program should be considered another "site". Therefore, always clear the browser cache when switching from one server demo program to another server demo program.

| CSP introduction | This is an introduction to the Barracuda Embedded Web Server with simple step by step examples. This is probably a good starting point for those new to the Barracuda Embedded Web Server SDK. |
| HttpResMgr | The HttpResMgr (Http Resource Manager) class can be used as a general remote file storage that can be accessed from anywhere. The HttpResMgr example shows you how to use the HttpDir, HttpResRdr, and HttpResMgr classes. The HttpResMgr example is a good starting point for gaining a broader understanding of the Barracuda Virtual File System. The HttpResMgr class can also be used as an alternative to FTP. |
| C/C++ Server Pages (CSP) examples | |
| Hangman 1 | A simple Hangman Game similar to the Hangman Game whitepaper. The Hangman Game in the whitepaper is in C++. This version of the game is in C code. |
| Hangman 2 | This is a more advanced version of the Hangman game, which takes advantage of Request Delegation to split the game into a number of pages that are combined into one during runtime. |
|
The Secure photo album |
This is an advanced example of how to set up user authentication and authorization by using the Barracuda Authentication and Authorization classes.
This is a C example. |
| Lua Server Pages (LSP) | |
|
The LSP Application Manager is designed as a boot loader for loading, starting, and stopping Lua Server Pages Applications in a running system. |
|
|
NetIo Server, Web File Manager Server, WebDAV Server, and more. |
|
| DHTML and EventHandler examples | |
|
Simple Debugger
C version |
The Simple Debugger example shows how one implements a simple execution trace debugger for an embedded system by using the EventHandler. |
|
Simple Debugger
C++ version |
The C++ version of the Simple Debugger. |
|
EchoPipe
C++ version |
EchoPipe shows how to set up and use an HTTP pipe. |
| WNMP | |
| WNMP | This is a simple demo program for the Web Network Management (WNMP) Barracuda plugin. |
| WebDAV | |
| WebDAV | This is a simple demo program that shows how the WebDAV plugin works. |
| Web Services with XML-RPC | |
| XmlRpc | XML-RPC, a simple yet powerful system built on XML and HTTP, lets developers connect programs running on different computers with a minimum of fuss. |
| Misc examples | |
| UploadFirmware | This example shows how to upload, extract, and install multiple components from a ZIP file. |
| ServerTcpCon |
Proprietary TCP connection over HTTP(S). This example shows how to Use the Web-server for initiating a proprietary (secure) TCP server connection. |
| The following is a list of miscellaneous code delivered as examples: | |
| Tools | A simple program for converting the "dat" file produced by CspLink into a large C array. This C array can be linked into your executable and be accessed by the web-server. The web-server can access the data in the C array by using a CspReader object. |
| FileReader |
The Filereader shows how one can create a CspReader and a ZipReader. The example code uses the regular file system for reading. Therefore, the classes are named FileCspReader and FileZipReader. You can customize these classes to read from, for example, ROM code such as Flash memory without the need of a file system.
CspReader is the interface between the Web-Server and the "dat" file produced by CspLink. The "dat" file contains all the data for CSP files. The "dat" file can also store regular html, gif pictures, etc., for diskless systems. The CspReader driver makes it possible for the web-server to fetch the web-pages from the "dat" file. ZipReader is the interface between the Web-Server and an instance of class ZipIo. The ZipIo class makes it possible to install ZIP files in the virtual file system. |
