Helicon Ape Free

From Helicon Tech: Helicon Ape Free is implemented as managed IIS7 module, but can be installed as .NET module on any ASP.NET-compatible IIS version as well. It works transparently for both server and client and can even be installed on a shared hosting account without administrative access. It literally implements Apache configuration model (like .htaccess and httpd.conf files) and all most demanded Apache modules in a single IIS add-on, not only making IIS compatible with Apache, but also extending it's functionality by a number of highly essential features.
