Also, have a look under your
$INSTDIR//webserver/tomcat/5.0.28_axis1.2/webapps/sgd/admin/loaddist
directory, and read through the swcd.jsp file. This provides a
load-balancing mechanism that you can use, and supports RR DNS as one
option.
If you prefer a RR DNS approach it can be a little touchy due to
certificate names; in particular, you can't allow connections to use the
load-balanced names, else you might get connections arriving at the
wrong server, not generally a good thing. The above jsp will help avoid
that as well.
There are a couple of ways to avoid SSL certificate mismatches when
using psuedo-names like, for example, sgd.soft.com. One way is to use
wildcards in your Servername - but I think we've decided the better
approach is to set the ServerAltName of your server certificates to be
the RR name, since most / all(?) browsers support this, and I think most
CA's can do this as well (self-signed certs can do it, too, with a few
changes.)
Some have redirects from http to https, you can do this with a bit of
mod_rewrite script like:
<VirtualHost _default_:80>
RewriteEngine on
RewriteRule ^(.*) https://tta1.example.com/$1 [R,L]
</VirtualHost >
Many people also want to avoid the standard Apache index page where
locale and client are chosen, and redirect users directly to the sgd
client url. After setting AllowOverrides, you can do something simple like;
Redirect /index.html https://servername/sgd
in a .htaccess file or replace index.html with something like:
<html>
<head>
<title> SGD Redirect Page</title>
<meta HTTP-EQUIV="Refresh" content="0; url=/sgd">
</head>
</html>
Just some options to consider - but definitely start with the swcd.jsp.

Dear SGD-Users,
Let say, i have installed and configured one sgd server with hostname
"sgd-01.soft.com". When the sgd server has been deploy, i will ask
all the users to access the sgd portal by typing http://sgd-01.soft.com.
Now, i have configured second sgd server with hostname
"sgd-02.soft.com". I have added this server as secondary to the
sgd-01.soft.com. Physically we have two sgd servers.
Definitely, user doesn't like to choose the sgd servers to access to,
like user1 type http://sgd-01.soft.com and user2 type
http://sgd-02.soft.com.
Question:
---------
1. What url address, i have to tell to the users so that they can
access to SGD portal ?
2. Can i do trick in DNS entry by adding sgd.soft.com and its refer
to sgd-01.soft.com and sgd-02.soft.com ?
3. What is the best practice for the above SGD setup ?
Appreciate if given some extra guides. Thanks.
