need several requests at the same time. So maybe pooling of
XmlHttpRequest(s) could work...
Btw, does dojo use pooling (since there was no leak with it) ?
Maybe it would make sense to check how they are getting around
this.

Don't know, might be worth checking. But dojo codebase is quite big and
the code little hard to read, mostly because dojo handles a lot of other
things (back button support, etc.)

Hi,
There is a browser-side memory leak in wicket ajax stuff when used
with internet explorer. We discovered it when changing our application
from wichet+dojo to wicket+wicket-ajax.
Memory leak occurs only if wicket-ajax is used in IE. With dojo,
there is on leak. Also, in firefox, neither solution leaks.
There is a simple example available at
http://download.syncrontech.com/public/wicketajaxleak.zip
It just displays a number, increments it and displays it again
using ajax.
There is also a memory usage graph which has data from
dojo and wicket-default ajax cases, from that it is easy
to see how differenty these implementations behave.
http://download.syncrontech.com/public/wicketajax.gif
These runs were done agains wicket 1.2-beta3.
This is a rather nasty problem for us, since we have a lot
of pages, which update themselves very frequently based on
data coming from automation systems.
We did some looking around in wicket-ajax.js but didn't
find anything obvious.
