A new admin interface added in 9.1 allows developers, hosting providers, and enterprise administrators to manage multiple instances of Lasso with ease: the main Lasso Instance Manager interface displays of a list of all known Lasso 9 instances on that machine. Below the list is a button allowing a new instance to be created quickly, and custom configuration applied to just that instance.

Each instance in the list shows:

  • Current licensing mode, based on the instance serial number, if any (runs in Developer mode if no license applied)
  • Current run status: red is not running, yellow is running but with a provisional license, green is running and fully licensed
  • Instance version

  • Instance details: instance name, description, url, home path, OS user, host pattern, disable instance, delete instance
  • Instance notes
  • Instance output log
  • Instance environment variables

FastCGI support makes it easy to connect to Apache, IIS, and most other Web servers. Manage users, data-sources, and email queues, adjust settings, execute SQL queries, and more. Free to develop in. Users purchase a license when going live with a website or where needing access internally across more than 5 ip's and 200 connections.
  • Document Mangement - Create, modify, combine, and serve print-ready documents in PDF, Rich Text, and other formats containing complex layouts which utilize tables, forms, graphics, and bar codes.

The latest version (8.1.0) is blazing fast. We develop and host solutions for some of the UK's largest blue chips. We could not get products to market as fast and as cost effectively without Lasso. With the release 8.1 it can now compete with PHP and ASP on performance grounds as well. Fantastic!!!

If you're a web developer and have never checked out Lasso, do yourself a favor and download one of their 30-day trials, or at least check out the online language reference at . It's available for Mac, Win, and Lin, and can connect to a wide variety of data sources. The core language is easy to learn yet very full featured. If I had to go back to any of the other web middleware languages I used to use, I think I'd just switch careers instead.

In my experience I've found the Fm Pro/Lasso solution an inexpensive, powerful and easy solution for those people wanting implement a database into their website. Especially for those companies who have used FM for a long time within and now wish to web enable their database.

Put simply with Lasso v5 I can produce products that compete with anything else on the market ... and still host all of our sites on WebSTAR Mac servers ..... it beats PHP and ASP into the ground ..... a fantastic product
