Aha, Bjoern's solution works! Testing the escaped ampersand by typing the
URI into the web browser destination doesn't work, but setting it inside a
<A HREF=> tag does.

Thank you for the solution to my problem. I'll try it in a number of other
places and report back if I encounter any problems (hopefully I won't).

Hm, I guess you didn't use <a
href='http://aqua.hba.marine.csiro.au:7272/CAAB/search/caab_search.search_pr
epare?scitxt=con&amp;ctg=37'>...</a>
but tried the URI instead. You have to escape the ampersand in the href
attribute, not in the URI itself.
