Actually with "prefix2domain(rewrite_mode, multidomain_mode)" the rewrite_mode value of 2: the user part of the URI is not changed. I don't know what I was thinking before, I actually tested this a few weeks ago and forgot about this parameter. So a better question here would be, can the PDT module store several hundred NPA-NXX records in memory?
