Helicon Ape

Helicon Ape is a piece of software developed by Helicon Tech to bring Apache functionality to IIS web servers. It executes as an ASP.NET module for IIS 7 (and higher versions), integrating the functionalities of over 35 Apache modules. This integration allows for the use of Apache configurations on IIS while maintaining the syntax intact, thereby extending the standard capabilities of IIS.

Aside from the introduction of Apache modules, Helicon Ape provides proprietary modules for server-side debugging and profiling (mod_developer), SEO optimization (mod_linkfreeze), and hotlinking protection (mod_hotlink).

Helicon Ape utilizes a graphical user interface for easy configuration (supporting directive auto-completion and spell-checking) and browsing. It also includes a regular expressions tester and a password generation utility.
