How to construct a web file browser?
set "Indexes" option to the directory in the apache config.
To learn how to build webapps in python, learn django.
Goal:  simple browser app, for navigating files on a web server, in a tree view.
Background:  Building a web site as a learning experience, w/ Apache, mod_python, Python code.  (No mod_wsgi yet.)
What tools should I learn to write the browser tree?  I see JavaScript, Ajax, neither of which I know.  Learn them?  Grab a JS example from the web and rework?  Can such a thing be built in raw HTML?  Python I'm advanced beginner but I realize that's server side.
If you were going to build such a toy from scratch, what would you use?  What would be the totally easy, cheesy way, the intermediate way, the fully professional way?
No Django yet please -- This is an exercise in learning web programming nuts and bolts.
