How do I enable HTTPS with LibHTTP?

You need to integrate OpenSSL and follow the OpenSSL.md guide, which involves setting up SSL certificates and configuring the server context for secure connections. This adds a step compared to servers with built-in TLS support.

LibHTTP vs Civetweb: which one should I use?

Both are MIT-licensed forks of Mongoose, but LibHTTP has diverged since 2016 with its own enhancements. Choose based on feature needs and community activity; LibHTTP emphasizes event-driven efficiency, while Civetweb might have different updates.

Can LibHTTP handle WebSocket for real-time apps?

Yes, it supports WebSocket for bidirectional communication, making it suitable for real-time features like chat or live updates in embedded C/C++ projects, as mentioned in the key features.

How to embed LibHTTP in a C++ application?

Include the library files, use the embedding API from Embedding.md, and refer to the provided examples. This involves initializing the server context and handling events in your existing codebase.

Is LibHTTP good for embedded Linux systems?

Absolutely, its lightweight nature and support for platforms like Buildroot make it ideal for resource-constrained embedded systems, often used for web-based configuration interfaces or IoT applications.

What security features does LibHTTP have?

It includes IP-based ACL, URL rewriting, file blacklisting, HTTP digest authorization, and optional client X.509 certificate authentication, providing robust access control for secure deployments.

What is libhttp?

LibHTTP is a lightweight, embeddable HTTP and HTTPS server library written in C/C++. It enables developers to add web server functionality to existing applications or deploy it as a standalone web server. The library solves the need for a simple yet powerful, multi-platform web server with support for modern protocols like SSL/TLS, WebSocket, and CGI.

Target Audience

C/C++ developers looking to embed web server capabilities into their applications, and end users needing a lightweight, standalone web server for various platforms including embedded systems.

Value Proposition

Developers choose LibHTTP for its permissive MIT license, ease of embedding, comprehensive feature set including SSL and WebSocket support, and cross-platform compatibility without restrictive licensing terms.

Overview

Multi platform HTTP and HTTPS library

Use Cases

Best For

Adding HTTP/HTTPS server functionality to existing C/C++ applications
Deploying a lightweight standalone web server on resource-constrained systems
Building embedded systems with web-based configuration interfaces
Implementing real-time communication via WebSocket in C/C++ projects
Creating secure web services with SSL/TLS and client certificate authentication
Developing cross-platform applications requiring consistent web server behavior

Not Ideal For

High-level web applications using frameworks like Node.js or Django, where native C/C++ integration offers no advantage.
Enterprise environments requiring extensive third-party modules or plugins available for Apache or Nginx.
Projects with teams inexperienced in C/C++ or event-driven architecture, as the API and setup assume low-level programming knowledge.

Pros & Cons

Pros

Permissive MIT License

LibHTTP uses the MIT license, allowing unrestricted commercial use without copyleft concerns, as highlighted in the README to ensure innovation freedom.

Cross-Platform Compatibility

It runs on diverse platforms including Windows, macOS, Linux, iOS, Android, and embedded systems like Buildroot, making it highly portable for various deployment scenarios.

Embeddable Design

With a clean API and embedding examples in the documentation, it seamlessly adds HTTP/HTTPS capabilities to existing C/C++ applications with minimal overhead.

Comprehensive Protocol Support

Includes HTTPS with SSL/TLS, WebSocket, CGI, SSI, and WebDAV, providing a full-featured web server in a lightweight package suitable for dynamic and real-time applications.

Cons

Forked Codebase Complexity

As a fork of Mongoose/Civetweb, there are potential compatibility issues and less community support compared to more mainstream servers, with the README warning against applying fixes from Mongoose to prevent GPL tainting.

Documentation Fragmentation

Documentation is split across multiple files (e.g., APIReference.md, UserManual.md), which can hinder quick onboarding and require more effort to navigate for specific information.

Dependency on External SSL

HTTPS support relies on OpenSSL integration, adding setup complexity and potential licensing or security management overhead, as noted in the OpenSSL.md guide.
