APEX

I want to use APEX in conjunction with Windows Small Business Server.

So... I have IIS running on Port 80 and APEX running on port 8080. I want to be able to access the APEX apps from the internet.

My question is (and I apologise if this is more an IIS question than an APEX question):

1) Can I do some config so that the user accesses my application through a URL like:

www.mycompany.com/myapp

instead of www.mycompany.com:8080/f?p=100

2) Can I do this in a way that means I don't have to open port 8080 to the internet.

I'm a Webserver (both IIS and Apache) newbie - so apologies if this is has a straightforward answer.

Thanks,

- Matt
