The amount of C code required increases when using the C Server Pages (CSP) plugin since CSP code is C code. The  Barracuda Embedded Web Server libraries and startup code can be embedded in your application or be compiled into a standalone server program on operating systems that support program loading. However, monolithic embedded systems require that the server libraries are embedded in the firmware code.,   lspapp:Your LSP application consists of LSP files that comprise your web application, i.e., pages that are compiled and executed on the server when accessed by web clients such as a browser. The LSP application can also contain pure Lua scripts that may be part of your web application or serve other purposes. For example, you may design applications that are part of your embedded system and that run in the background. These applications may or may not interact with the web application. Examples of non-web applications are applications using our high-level socket API or applications that run in the background and interact with your device. The LSP plugin also supports an application concept where you can dynamically start and stop applications. You can also dynamically upgrade applications in a running system. One application is typically assembled as one ZIP file.  You can have any number of applications running simultaneously.,   lsp:The Lua Server Pages (LSP) plugin is the bridge between Lua scripts and the Barracuda Embedded Web Server API. The Lua bindings make it possible for Lua scripts to call the C functions provided by the Barracuda Embedded Web Server and the various C implemented plugins such as WebDAV. The API is extensible and you can add your own device management functions to this API by either manually designing Lua bindings or by using our online Lua binding generator that automatically creates Lua bindings from your C header files. See the products page for more information on the Lua binding generator.,   plugins:The Barracuda Embedded Web Server comes with a wealth of plugins that can be dynamically managed from Lua scripts. For example, one can dynamically add Resource Readers, File Managers, etc. to the Virtual File System.,   luavm:The Lua virtual machine (VM) is responsible for compiling and executing Lua scripts. The Lua VM, which is included with the LSP plugin, also provides a set of functions that are portable across all platforms supported by the Barracuda Server. Our version of the Lua VM is slightly modified to better fit embedded systems and the APIs provided by embedded operating systems.,   IoIntf:The I/O interface provides a common set of functions for working with files stored in various media types such as data stored on a standard file system, ZIP files, and network files. The I/O interface is an abstract type used by various types of plugins such as the Resource Reader, the WebDAV plugin, and your Lua scripts. I/O interface implementations include the NetIo, the ZipIo, and the DiskIo.,   sqlite:The Barracuda Embedded Web Servers database plugin consists of the free SQLite database engine and Lua bindings that make it very easy to create database-driven applications in Lua. The database plugin is designed for high-level (Posix) compliant operating systems such as QNX, (embedded) Linux, and Windows.,   SharkSSL:The SharkSSL server is used by the Barracuda Server and the SharkSSL client is used by the optional plugins such as the SMTP library, HTTPS Client library, etc. In addition, the high-level socket API is pre-integrated with the SharkSSL client and server. We also use SharkSSL for enabling AES ZIP file encryption for the ZIP file system plugin, a feature commonly used by device manufacturers when designing their firmware upgrade logic. In addition, a number of high level encryption APIs are available via the LSP plugin.,   NetIo:The NetIo is similar to a network file system and makes it possible for a Barracuda Embedded Web Server to access resources on another Barracuda Embedded Web Server. The NetIo is typically used during development. The embedded device uses the NetIo client and connects to a Barracuda Embedded Web Server running on your PC/Workstation. The benefit with this setup is that you can keep all web resources, including LSP files, on your PC during development. As an example, an LSP file accessed via the NetIo is loaded from your PC, compiled on the fly, and executed automatically on the embedded device when the resource is requested by a browser. ,   ZipIo:The ZipIo makes it possible for the web server and application code to work with resources in a ZIP file as if the ZIP file is a read-only file system. The ZipIo is typically used for deployed applications i.e., for applications that are tested and completed. ZIP files can be stored on a regular file system, directly in flash memory, or be embedded inside the executable. You can create multiple ZipIo instances, and you can have a system that uses a combination of ZipIos, DiskIos, and NetIos simultaneously. You can even bridge a ZipIo via a NetIo.,   DiskIo:The DiskIo is an implementation of the abstract I/O Interface that interfaces the server to a regular file system. In other words, the DiskIo makes it possible for the web-server and application code to work with resources on a standard file system. We provide many DiskIo implementations for a multitude of embedded and non-embedded file systems.,   server:The application server framework is responsible for delegating (finding) the requested resource in the virtual file system when the HTTP engine has completed parsing an incoming request. The virtual file system typically deals with resource collections and not directly with the physical resource. The plugins installed in the virtual file system are the resource collections responsible for the individual physical or non physical resources. Unlike a web server, a resource in the Barracuda Application Framework does not have to be a physical resource. Physical resources are dynamic Lua Server Pages or static content such as HTML files, images, etc. Nonphysical resources are virtual file system directory functions that are either implemented as C code or as Lua code.,   ThreadPool:The optional thread pool makes it possible for the server to manage concurrent requests. The thread pool is typically used by LSP pages and CSP pages. However, not all resources utilize the thread pool. For example, the resource reader uses asynchronous sockets i.e. non blocking sockets.,   HttpEngine:The HTTP engine is responsible for parsing the incoming HTTP request. The HTTP engine is also responsible for maintaining the advanced HTTP 1.1 state machine which resembles process scheduling in a real-time operating system. A web server connection can be in four states: disconnected, idle, ready, and executing. Idle connections are persistent HTTP 1.1 connections waiting for a HTTP 1.1 compatible client to issue the next request. Ready connections are connections with pending incoming data and are scheduled to execute as soon as a thread becomes idle. Executing is any connection executing in a thread. The number of allowed connections and threads is configurable.,   rtos:The server and the plugins require a number of kernel primitives such as thread management, mutexes, and semaphores. A porting layer is provided that interfaces to the various embedded and non-embedded operating systems supported by the server.,   TcpIpStack:The server and the various plugins require a TCP/IP stack. A porting layer is provided that interfaces the servers internal TCP/IP API to the native TCP/IP stack. We support a wide range of TCP/IP stacks ranging from BSD-based TCP/IP APIs to nonstandard and/or fully asynchronous TCP/IP APIs.,   FlashMem:Deployed LSP applications (ZIP files) can be stored directly in flash memory on devices without an embedded file system. It is for this reason not necessary to use a file system for storing web resources such as HTML files, images, LSP files, etc. since these resources when packaged as a ZIP file, can be stored directly in flash memory.,   FileSystem:Most high level operating systems come with a file system, but many embedded devices are used without a file system. Using a file system with the server is therefore optional. Web applications can be stored as ZIP files directly in flash memory. However, a file system is required when using plugins such as the WebDAV server.}$(function() {   var xOffset  450;   var yOffset  350;		   function setTooltip(e) {      var tt$(#tooltip);      var xe.pageX-xOffset;      if(x  1) x  1;      else if(x > 400) x  400;      tt.css(top,(e.pageY-yOffset)+px).css(left,x+px);      return tt;   };   $(area).click(function() {return false;}).      hover(function(e){console.log(info$(this).attr(bainfo));         setTooltip(e).html(info$(this).attr(bainfo)).fadeIn(fast);      },      function(e){         $(#tooltip).stop(true,true).hide();       }).      mousemove(function(e) {         setTooltip(e);      });});/script>        !-- /main content -->      /div>    /div>                                                            br styleclear:both; />  /div>div idfooter>div classcontainer>div classcopyright>a hrefhttps://realtimelogic.com>Real Time Logic © 2025/a>/div>div classnotice>a hrefhttps://realtimelogic.com/contactus/>Contact Us/a>/div>/div>/div>script async srchttps://www.googletagmanager.com/gtag/js?idG-L47MWRVEY0>/script>script>  window.dataLayer  window.dataLayer || ;  function gtag(){dataLayer.push(arguments);}  gtag(js, new Date());  gtag(config, G-L47MWRVEY0);/script>/body>/html>
