The following program accesses an EDB database. It appears that Session.BaseURL and Database.BaseURL are determined when On Authentication is completed and is only valid if the session is Authenticated. Is this correct? I do not understand why the following results in access to the database via the Database.BaseURL.

Instance 1

Application.Title: Eyre & Smith Stock Database
Application.Version: 3.02b
Database.DatabaseName: esStock
Database.BaseURL: /databases/esStock
Session.BaseURL: /
Session.AuthenticationResource: authentication
Session.Authenticated: True
Host:  
Port Number: 0
Default Port Number: 0

Instance 2

Application.Title: Eyre & Smith Stock Database
Application.Version: 3.02b
Database.DatabaseName: esStock
Database.BaseURL: http://localhost:8300/databases/esStock
Session.BaseURL: http://localhost:8300
Session.AuthenticationResource: authentication
Session.Authenticated: True
Host: localhost
Port number: 8300
Default port number: 8300

Instance 3

Application.Title: Eyre & Smith Stock Database
Application.Version: 3.02b
Database.DatabaseName: esStock
Database.BaseURL: http://wck:8301/databases/esStock
Session.BaseURL: http://wck:8301
Session.AuthenticationResource: authentication
Session.Authenticated: True
Host: wck
Port number: 8301
Default port number: 8301

Occasionally, when the application starts, I receive an Application Error “Request execution already in progress”. How am I supposed to handle this? Presently, when I click on the OK button, the application happily continues, the user is authenticated the user and the application displays the database data. So apart from the message appearing, it appears to be working OK.

No, that is not correct.  This information is in the manual:

<< I do not understand why the following results in access to the database via the Database.BaseURL. >>

Please do not make me parse the meaning of your questions - what do you not understand, specifically ?

<< Occasionally, when the application starts, I receive an Application Error “Request execution already in progress”. >>

This means that you're trying to authenticate (using the TSession component) while the TSession component is already in the process of authenticating.  You need to re-check your database code to make sure that you aren't trying to perform database operations *before* you have actually been able to authenticate successfully.
