[Seaside] How do I get the base URL? I want to send out an email with a link

requestContext request url doesn't return the full URL for me. Here's what I ended up doing:

	| url request |
	applicationUrl ifNil: [
		request := self requestContext request.
		url := request url withoutQuery.
		(self application url relativeTo: url) do: [ :each |
			url path removeLast ].
		applicationUrl := 'http://' , request host , url asString ].
	^ applicationUrl.

Then my WAComponent subclass just delegates to 'session applicationUrl'.

I have some objects that aren't WAObject descendants at all, so I made a WAObject subclass called ARPApplicationConfig, which I added applicationUrl as a class method to, and then it uses the singleton pattern to create a new instance and delegate applicationUrl to that instance.  So in my other objects that need access to the URL, I can just call  'ARPApplicationConfig applicationUrl'.

Thanks everyone for the input.  I'll report back if I run into any problems with it.

I found  WAApplication#url which sent me on an interesting journey...because when I did "self halt" inside of a WAComponent subclass and ran "self application" then I get a WARequestContextNotFound error, although apparently that's only when I launch a debugger.

How can I get the full URL?  I don't want to hardcode it...I assume I should be able to get the base URL of my application from somewhere but I'm not sure.
