I'm investigating a simple url rewriting setup for iis6 / net 2.0 sites.

I've added a . wildcard mapping in IIS that points to the .net executable. I'm also using the urlMappings element in the web.config to add some rewritting urls. I've moved the config outside of the web.config so I can make changes to the list without forcing application restarts, like so:

  <urlMappings configSource="config\urlMappings.config">
  </urlMappings>

I'd like to allow our content management to add urls to this file so that we can have extensionless friendly urls.

<add url="~/someurl" mappedUrl="index.aspx?page=123" />

This works just fine, but I'm concerned about limitations in the number of entries that I can map in the urlMappings config. I can't seem to find any documentation on this. Has anyone found any limitations?

Thanks.
