Multi-Lingual Site, will this strategy work

I am doing a site for a client in Italy. By default, the site will be in English. I want to also offer German and Italian versions of each page. The site is small enough that I can script it so each page will display language based text determined by a Session variable. Ok, so here is my question. On each page, I will have three links, Italian, German, and English. When the links are clicked, regardless of the page they are on, a script will set the session variable appropriately and redirect back to the EXACT same page BUT with a variable appended to the URL, like this:

www.mysite.com/local-area.asp for English

www.mysite.com/local-area.asp?l=i for Italian

www.mysite.com/local-area.asp?l=d for German

My question is that will the various search engines pick up the respective languages and index them, such as google.de, google.it, etc? The actual links on the top of each page would look like this:

<a href="scripts/languages.asp?l=e"> English </a>
<a href="scripts/languages.asp?l=i"> Italian </a>
<a href="scripts/languages.asp?l=d"> German </a>

If the links are static (like at the bottom of your post) then you should be ok. But if the "click" triggers some sort of (complex) javascript, then that redirect is probably not clear to bots. If that's the case, then you should really ALSO include the set of static links on the same page, either visible (e.g. as a footer) or maybe inside a NOSCRIPT tag. If you don't really spam the noscript tag, then it would be fine - better still: recommended - to do that...

Surely there's a way to make ASP "server side include" a set of static-looking links to the same page you're on, but with the parameter added...
