Up to now, I've been assuming that the top-level application class had
its own instance per connection.. Is my assumption correct or is this a singleton class? I just want to make sure my current thinking is correct..

Assuming we're talking about WAApplication it is one instance per URL. This instance in concurrently accessed.

Just a few more questions.. I went and checked my main top-level class and its derived from WAComponent and not WAApplication.. This code was originally developed in Seaside 2.5 and moved forward to version 2.8 now.. Should I instead be using WAApplication? Also, when you mention one instance per URL, can I equate that to be one per Seaside application or can it be associated with connections? Your wording above sounds like its one per Seaside application, but I wanted to double-check.. Currently my code assumes its one instance per connection and has a 'content' object.. I want to ensure that IF this is a singleton then I need to refactor things a bit to ensure this 'content' object moves elsewhere..

However there rarely should be any need write your own WAApplication class. > Also, when you mention one instance per URL, can I equate that to be > one per Seaside application Yes, WAApplication is the seaside application you find at a particular URL.

I want to ensure that IF this is a singleton then There are only very few singletons in Seaside (because they suck) and they don't include WAApplication or WAComponent. The root component class is instantiated when a new session is created and bound to this session. From there other instances of WAComponent are created on demand and bound to the root component instance.

I'll stick with my main component residing as a WAComponent for now. >> Also, when you mention one instance per URL, can I equate that to be >> one per Seaside application > > Yes, WAApplication is the seaside application you find at a particular > URL.

This is enough info to allow me to continue refactoring a bit..
