I'll start with the latter question - what does an HTTP server give 
you? First, it allows you to run CGI apps. Second, sure, you can use 
a FILE: protocol to access the HTML files in the IFS, but you can 
only go so far with relative path names. Third, you'll need to know 
how to work with an HTTP server when you build an external web site 
anyways, so you might as well learn that right away.

Regarding the rest of your note, there's no one roadmap that's right 
for everyone. There are a lot of things you can learn, lot's of 
paths up the mountain. For me, here's more or less the path I've 
followed over the past five years or so: Java, HTML, HTTP server and 
Linux, Perl and CGI, Python, XML (to name just a few).

Others will certainly provide iSeries-specific recommendations. But 
if you can, try to learn things that have applicability elsewhere, 
as well as on the iSeries. Others may disagree (some strongly!), but 
here are my specific recommendations:

When learning HTML, go straight to XHTML strict and CSS. Better to 
learn how to do things right, right from the start.

If you want to learn CGI, learn Perl. It's the most gawd-awful 
language out there, but the best CGI experience is among Perl 
programmers. If you have a question on CGI and serving up web pages, 
the best answers are often described in terms of Perl. You may not 
actually want to or have to use Perl, but whatever language you 
actually do CGI programming in, understanding Perl is a definite 
asset. (Who knows, you might actually LIKE Perl!)

Remember that you can run Apache on your own PC. (At least, you can 
on a Linux workstation.) So, you can experiment all you want with it 
on your PC before deploying a web site on your iSeries.

If you want to have *fun* programming, learn Python. It's probably 
also the best way to learn OO, if that's on your longer term wish 
list. It's the language I use at home for almost all of my casual 
programming, since my spare time is very valuable to me. I even 
occasionally use it for some things at work.

For all of these things, there are good web sites that offer 
introductions, tutorials, and FAQ's.

Cheers! Hans
