Add support for parametrizing the base path

[borjapazr]

Is your feature request related to a problem? Please describe.
Currently, the application does not allow users to parametrize the base path, which makes it difficult to configure a reverse proxy with path routing. This lack of flexibility can hinder deployment in certain scenarios and configurations.

Describe the solution you'd like
Please add support for parametrizing the base path within the application's configuration. This feature would enable users to set up a reverse proxy with path routing more easily and allow for seamless integration with various deployment environments. Ideally, this should be done in a way that doesn't break existing configurations.

Describe alternatives you've considered
I have considered using URL rewriting to work around this limitation, but it's less efficient and can potentially cause issues with certain configurations.

Additional context
The ability to parametrize the base path is a common feature in many web applications and would greatly improve the flexibility and ease of deployment for the answer application. By supporting this feature, we can ensure that the application remains adaptable to a variety of infrastructures and configurations.
