getting absolute local path to a cached file

[iwuser]

I'm adding temp files using something like:

sTempFileName := TIWAppCache.StreamToCacheFile(self, ...

And sTempFileName works fine as a URI (i.e.: in a IWURLWindow1.URI), because it's a valid relative URI.

But I need to get a local absolute path to this file in the server-side code, hopefully easier than parsing WebApplication.UserCacheDir, etc.

Is there a direct way of doing this?
