4D, Inc. has continued applying pressure to the idea of using Mac OS X’s built-in Apache Web server with this week’s release of WebSTAR 5.1. Most notable among WebSTAR 5.1’s new features is the integrated 4D WebSTAR Rewrite plug-in (based on Pardeikes Welcome Plugin for earlier versions of WebSTAR). We use Welcome heavily for virtual hosting, redirecting URL requests on the fly, transparently rewriting URLs (replacing ugly Lasso URLs with our permanent GetBITS URLs) and more, so its inclusion in WebSTAR 5.1 is extremely welcome. Along with bug fixes and performance, compatibility, and usability improvements, other new features include support for the FastCGI gateway interface, automatic language negotiation based on browser preferences, a speedier new WebSTAR Admin client, a new WebObjects adapter, and improved search summaries. The 46 MB update is free to registered users.
