RevServer deployment on OSX Server

Thanks Jaque but it looks very much like revServer, the LiveCode architecture and IDE simply aren't designed to support development and deployment of thin client, standards-based web applications.

If revServer is just a CGI in that scenario, I might as well use PHP - which is live, recognised, respected, broadly supported with tools frameworks and user communities.

It's 'horses for courses' and I got on the wrong one! ;-)

There are bug fixes in 4.x of course and some added commands and syntax that might be useful depending on what you need to do.

Avoiding the older CGI tedium is a huge plus. Like I said, if you have ever tried to debug a CGI you are in for some major hair-pulling. And constructing HTML from a CGI is tedious, verbose, and often requires templates stored on the server which have to be read in and altered by script. Generating HTML from a CGI requires pages of "&quote&" syntax or merges. And then there is the astronomical number of trips back and forth between your server error logs -- which tell you almost nothing about what's really wrong -- and your text editor, which is where you'll be writing your scripts.

No translations or merges are necessary. Irev allows you to set a global flag that will put error messages right into the browser where you can read what's wrong immediately. IRev pages load as normal URLs like other web pages, without needing to call out to the CGI-bin directory.
