We have a Qt app that when it starts tries to connect to a servlet to get config parameters that it needs to keep running.

The URL may change frequently because we have to test the application in several environments. Right now (as a temporary solution) the URL is a constant in source code, but it is a little bit ugly.

Where is the best place to mainting this URL, so that we do not need to change the source code every time I want to change the environment target?

In a database table maybe (my application uses a SQLite DB), in a settings file, or in some other way?

Thank you for you replies.

    You have a number of options:

    1. Hard coded (like you have already)
    2. Run-time user input
    3. Command line arguments
    4. QSettings
    5. Read from a bespoke file as text.

    I would think option 3 would be the most simple to implement without being intrusive, but it does depend on what kind of application you have.
