Hi Racke,

After some research I found an old post that referred to adding an alias to
/ on the catalog parameter in interchange.cfg

eg my catalog was called with:-

Catalog       mycatalog /home/mydir/catalogs/mycatalog /cgi-bin/mycatalog

adding a / alias to the end appears to have fixed it:-

Catalog       mycatalog /home/mydir/catalogs/mycatalog /cgi-bin/mycatalog /
Although this appears to have fixed the problem I get an odd message when
starting interchange, the server has 2 catalogs and the second already had
an alias to / and was working fine with rewrites, when I start it now it

Configuring catalog mycatalog2...Using MySQL,

Configuring catalog mycatalog...Using MySQL,
DSN=dbi:mysql:mycatalog_mycatalog...Alias / used a second time, skipping.

So although it works it claims to be skipping this alias, is this not really
the correct way to do it?

Or does the alias to / only need to be listed on the first catalog in
interchange.cfg and it then works for all catalogs below?
