Subject: global variables /rexml / caching

A recent thread talks about using a global class to
tuck variables in rather than have them polute a
namespace. I think this is a good idea(and is one of
the reasons java simply does not allow it).

I keeping all my 'globals' in an xml file using
rexml.. like db connects, prod flag, etc. Right now
this file is loading everytime (until I can figure out
how to cache it). I least i thot it was not caching...

I have are toolbar items in my global
xml.<toolbar><items/><toolbar> and when i'm outputting
them, i check to see of the client is logged on or off
and create, on the fly, an  element accordingly, and
append it to items. However, if i refresh, i find that
these elements are accumulating. When i output the
rexml, indeed, they are accumulating but i do not know
why. It's either looping over my logic(don't know
how!) or it's caching the xml file for some reason.

<code>
#Are we logged on?
#Dynamically add an element to the globals for the
toolbar	
#To show logon or off

eItem = REXML::Element.new 'item'

if $sess.data['on']to_i == 1 then

	eItem.attributes['name'] = 'Logoff'
	
	eItem.text    = "/?cnt=adm/logon/index&logoff=1"

else

	
	eItem.attributes['name'] = 'Logon'
	
	eItem.text    = "/?cnt=adm/logon/index"				

end

eRight =
$global.root.elements['Html/Toolbars/Main/Right']

eRight << eItem

#s = ''
#$global.write(s,1)				
#print CGI.escapeHTML(s)

print $html.formatToolbar eRight
				
</code>

As anyone experienced this. I would sure like to cache
it at some point but wish i were doing it on my own!

:P
