2) The only URL you can have end in a forward slash is the one that will return the default index page. And you can have only one default index page per web directory. All other pages must use a URL the includes the page name. The extension (.aspx) is used by IIS to route the page to the correct rendering engine. This one you can't avoid since this is how URLs and requesting pages works.
I am working on something similar but didn't know what route to take.
If I'm hearing centauricw correctly, you are saying you can not change the url name?
Someone suggested to me to create new directories like so:
Then create a new page, adding the source code from the exsisting aspx page, and name it index.aspx.
then put it into that subsubfolder or where ever you need it.
That way you have your url as you need it and can redirect the old url to that one.
