There's a tremendous performance hit involved in loading two languages
in a single asp page. The language in the "<%@language = .." tag is
the default; the other language (loaded through a "<script runat='server'
language='..'> tag?) seems to take extra long to load, and seems to
load & unload for each <script> tag. Also, there's no guarantee of
order of evaluation of the two languages.
If at all possible, scrap any VBscript on the pages where you need
Perl (and vice-versa). I use perlscript with IIS 4.0 all the time;
yeah, it's slower than VB (so is JavaScript, for that matter), but
I try to never mix languages on a page. You can, however, have pages
with different <%@ languages in the same application with no additional
performance penalty.
