What's H2O?
H2O is programming made for the web.

What's it like?
H2O is English-like. If you know some Perl, VB, ASP, or PhP you'll be immediately productive in H2O. It runs on Linux, Mac, Unix, and Windows.

How do I try it?
Download H2O for free. Get it from hosting providers. Or buy online.

Where does H2O come from?
The language was invented by Aestiva. H2O stands for:
   HTML with
   HTML/OS
   Overlays.

Distributed Computing

H2O technology includes built-in distributed computing. Each copy of H2O operates as a network node capable of reading and writing to files located on other copies of H2O. Once two copies of H2O are set up to talk to each other (this is done in the H2O Control Panel), networking is available.

To read or write to a file across a network you precede the file name with the name of the node. For example:

COPY FILE="B:/mylist.txt" TO mydata /COPY

To transport a user from one node to another you write a link to the web page on that node, for example, a standard HREF link would be written as:

<A HREF=B:/cart.html>My Cart</A>

When users move from page to page in H2O they retain their variables. This feature is true if they stay on the same node or not. Applications consisting of many web pages can reside on a single node or across many.

The approach used by H2O is web-centric. More importantly the approach is simple, familiar and does not require the installation of SOAP, CORBA or other add-ons unavailable in all environments. H2O's web-networking works everywhere H2O works -- on different platforms, in shared hosting accounts, on different kinds of hardware, and on networks where non-web ports are blocked.
