RE: [Slashcode-general] Multiple Slash Servers

[Martin, J. S. <Jam...@di...>]

The reason I bring this up is because if you haev 2 Web servers pointing to
a database server and the Web Servers are sitting behind a Cisco Load
Director (load balancing hardware).  It seems as though it's almost an
oversite in the code that the absoulte and relative dirs are hardcoded into
the database.  The absolute and root dirs should be generated by the perl
scripts on the web server based on either a config file or generated by the
"hostname" command.  I've tried hardcoding the Utility.pm module to get this
to work, as far as I can tell a constants hash is created with all the
variables pulled from the vars table.  I tried to modify the Utility.pm--
there is a subroutine called root2abs in which it retrieves the rootdir from
the database and makes it into the relative dir--instead of it pulling it
out of the DB I hardcoded it to the 2nd webserver and it still would not
take.  If I could just find where exactly that the code is pulling that
information from the DB, I could hard code it on the 2nd machine so that it
would work.  Right now my crappy solution was to start the first server,
modify the rootdir variable in the database to point to the 2nd server, and
then start the 2nd server.  It seems to work that way, but it's not
favorable for obvious reasons.

Uhmm, yes, you are right. I haven't think about that. But you have the
problemas that Martin has shown with the domain name, the cookie domain
also ...
