It's quite simple to route a request to another server by adding just a few Apache directives that cause it to act as a reverse proxy for certain urls instead of processing them itself.
A potential drawback is that it always authenticates every request to the other server using the a single set of credentials for a nominated user which must be base64 encoded into one of the reverse proxy directives (which is not difficult)
However if you considering using a custom page on the other server instead of one of the existing pages then you can embed the username as clear text in the url which the custom page could use derive information from the database for that user.

Cheers, Peter

That is exactly what we do for single sign-on. It seems to satisfy even the most security conscious/paranoid of clients we have. Usually sent as post data rather than on the URL as a get though.

Paul,

How about embedding the the user ID and password in the URL, but encrypting it? Many encrypting algorithms return binary data which would not be suitable. I handle that by converting binary to base 64. It's still strong encryption. Your application on the other end would obviously need to know how to decode it.

Subject: [WEB400] Single Signon With Different Web Servers

We have a customer with an existing customer portal solution.
Customer signs in with account number and password to a JBOSS server. This allows
customer to see their account data and other customer information. We
plan to deploy on a new application to a different Tomcat server
within the same network. Customer requires a single signon amongst
the 2 applications. IE... After signing on the 1st JBOSS
application, they want to present a link to the new application but
don't want to make customer enter account number and password again.
The new application needs access to the account number and password in
order to lookup customer equipment and account information. We
obviously need to make sure it is secure and don't want to pass
account numbers and passwords on a URL. We do plan to use SSL.

We are looking for ideas on how to best enable this requirement.

Thanks Paul Holm
