Author: Stefan Frings QtWebApp supports you in writing server-side web application in C++ based on the Qt framework. It is a light-weight implementation inspired by Java Servlets.

Features:

stefanfrings::HttpListener is a HTTP 1.1 web server with support for
- HTTPS
- IP v4 and IP v6
- persistent connections
- pipelining
- file uploads
- cookies
- dynamic thread pool
- optional file cache in stefanfrings::StaticFileController
- optional sessions via stefanfrings::HttpSessionStore
The stefanfrings::Template engine supports
- multi languages via stefanfrings::TemplateLoader
- optional file cache via stefanfrings::TemplateCache
- for all text based file formats
The stefanfrings::Logger classes provide
- automatic backups and file rotation
- configurable message format, see stefanfrings::LogMessage
- messages may contain thread-local info variables
- optional buffer to improve performance and reduce disk usage
- apply configuration changes without restart

If you write a real application based on this source, take a look into the Demo applications. They set up a single listener on port 8080, however multiple listeners with individual configurations are also possible.

To set up a HA system, I recommend the use of an an Apache HTTP server with proxy balancer and sticky sessions.
