javascript example plus cgi on server. next step is...

[sartic]

I learn how to pass parameters to my app on server (test example is server lighttpd with enable cgi support and javascript form in browser).
I can even send binary files (example uploading images to server and resizing before saving in archive).
Next step is pretty output. I have raw text only with <br> for nl.
I would like to generate nice pdf ouput from my cgi program or at pretty html output.
Is there any work done in pb for this or send me links to read.
Thx
