Introduction
This example requires :
- PEAR::HTML_Progress 1.1 or better.
This example allows you to upload files from a web browser to your web server
and logs operations.
PEAR::HTML_QuickForm package is used to make and manage the form that will send file
to your web server (top frame), while HTML_Progress is only used to display a horizontal
progress meter running in indeterminate mode (bottom frame).
Be aware that your web server could returns a timeout on long upload operation, by running
the HTML_Progress script (See technical notes below).
To logs all file uploads, we used the observer pattern with HTML_Progress_Observer class.
Results are written in a series of files 'http4_[iso date].log', where iso date
corresponding to current date in format YYYY-MM-DD.

Technical notes
The script time-out refers to the number of seconds a PHP page is given before the script
is assumed to have failed and the page terminated.
If you are uploading a large file the script that is receiving the transfer may time out
before the file has been completely uploaded.
To alter this setting you should insert the following code into your uploading page
prior to creating any HTML_Progress and HTML_QuickForm objects.
Render options
increment = 10 (to make progress bar animation smoothest in indeterminate mode)
HTML_Progress::setIncrement()
speed = 100 (to make progress bar animation smoothest)
HTML_Progress::setAnimSpeed()
color = white
with = 1px
style = inset
HTML_Progress_UI::setBorderAttributes()
