Not sure if it is exactly what you want, but we needed to add some
"landing pages" for our seaside app, where you can have parameters
coming in from other applications.
For this, we used initialRequest: in our registered main component.
There you can access parameters of the request and react to them using
request at:ifPresent: for example.
To "call" into your app would then look like this:
http://yourApp?Parameter1=value1&Parameter2=value2
Please be aware that this is out of session context. But I guess this is
clear anyways.
