[Seaside] Multiple entry point best practices

[Ramon Leon]

> I'm building an application that will have different entry 
> points.  It will be structured like this:
> 
> main (MYMainComponent)
> -users (MYUserComponent)
> -photos (MYPhotoComponent)
> -places (MYPlaceComponent)
> 
> This will allow users to bookmark, say, a photo with a url 
> like '/seaside/myapp/photos/243'.
> 
> I need all four to share the same application header, footer, 
> and session so that it's one continuous application.

Host your app in Pier, it has bookmarkable urls.
