The 2.6 version of MacHTTP for Mac was available to download on the developer's website when we last checked. We cannot confirm if there is a free download of this app available. The application lies within System Tools, more precisely General.
From the developer:
MacHTTP is an opensource Mac HTTP server for both PPC and 68K Macs. The new version now includes user-defined actions (allowing multiple URLS to be mapped to a specific CGI), folder aliases, Thread Manager support, performance tuning parameters, Windows virus rejection, and other improvements.
