The yaSSL Embedded Web Server is a fast, embeddable, and easy-to-configure Web server with a strong focus on portability and security. The Web server offers SSL/TLS (HTTPS) support built-in through the CyaSSL embedded SSL Library. With a footprint size of less than 100kB with SSL enabled (or 40kB without SSL) and a simple and clean API, the yaSSL Embedded Web Server was designed to fit perfectly into resource-constrained embedded environments. While maintaining a small size and fast speeds, the yaSSL Embedded Web Server offers a full feature set to give you the maximum amount of freedom and flexibility when developing your project.
Serv-U is a powerful and easy-to-use file server which supports the FTP, HTTP, and SFTP (via SSH2) protocols to ensure maximum compatibility with the widest range of transfer client software. It supports SSL encryption, provides a Web-based interface to allow administrators to remotely access and configure the file server, includes a built-in transfer client to allow users to upload and download files from their Web browsers, provides photo sharing capabilities, integrates with Active Directory (providing levels of security based on Organizational Units), and can be accessed and administered in 13 different languages simply by choosing an appropriate language upon login.
Alaya is a primitive chrooting Web server with basic WebDAV support. It can serve HTTPS and HTTP, and can authenticate using PAM, /etc/shadow, /etc/passwd, or using its own authentication files that allow for 'native' users that only have access to alaya content. It's intended to be a simple method of sharing content over WebDAV, and though it can be configured with a config file, it's easy to configure by command-line switches alone. Alaya always chroots to ensure that malicious users can't use '..' within a URL to access unintended documents, and that users can't accidentally leave documents in places outside of the chroot. It has a 'ChHome' mode that chroots users into their home directory and serves content from there. It supports .cgi scripts out of a trusted path (so not from within the chrooted WebDAV share) and read-only shared directories that are outside of the chroot (allowing access to shared content when in ChHome mode).
