SID-01844: Setup a topic to be rendered in the background

I have a WebLeftBar that includes a tree of the whole site. In order to speed things up I'd like the tree to be generated in a background job and included on display instead of constructed anew on every page load.

I imagine that to do this I should make a Twiki topic that generates the tree. This will be loaded by a cron script every couple of seconds and written to disk. Then I modify the view template to include the generated page in WebLeftBar.

Any tips? I'm sure this pattern has been applied by others so I thought I'd ask before implementing it anew.

Thanks

Discussion and Answer

I went ahead and wrote a little script that calls expandCommonVariables on the given topic and writes the result to disk. However, my web restricts TWikiGuest access and the script appears to run as guest. How do I make a script run as admin?
