Re: [cgiapp] dynamic stats and progress bar for file uploads

[Cees Hek <suppressed>]

Well, thanks to a miserable day outside, and a few hours that I
probably should have spent doing real work, I made an attempt at doing
the upload meter today.

It still needs a bunch of work to clean things up, but it is in a
working state.  I think it can easily be abstracted into a module that
can then be used from within CGI::Application.

I did run into a few annoying hurdles along the way.  In order to use
the upload_hook in CGI.pm, I needed to pass the hook information when
the CGI object was created.  This meant overriding 'cgiapp_get_query'
and creating a custom CGI object.  I don't know how well that will
work in a plugin!

The surprising thing is how easy it was to setup the AJAX stuff, that
took all of 30 minutes of searching the internet, reading and copying
a couple simple examples.  The tough stuff was getting the upload_hook
stuff working properly.

Anyway, you can try it out here: 
http://cees.crtconsulting.ca/perl/examples/uploadmeter/

If anyone wants a look at the perl code, send me a note, and I'll post
it as is.  Otherwise you will have to wait for another rainy day when
I can finish things off properly :)

Cheers,

Cees
