Multiple requests for clear.cache.gif

[arozsypal]

Hi,

I am using GWT 1.4.59 (but I also had the same issue with 1.4.10). I
am facing a strange problem when using Tree widget. In IE6 loading a
tree is considerably slower than in Firefox or IE7. I found that each
time I add a child item to the tree, the browser loads from the server
6270670BB31873C9D34757A8AE5F5E86.cache.png (probably image bundle
containing the tree_open.gif, tree_close.gif, and tree_white.gif),
then clear.cache.gif.

Any ideas how to avoid these unnecessary roundtrips to the server?
Would making the .png file cacheable in the browser help?

The solution is actually quite well documented in the GWT
documentation itself. It really is an issue of caching. You can read
