Don't know if there's a better way, but this should work I suppose:
Go to serverOne and share the subfolder where text.html is. Then on serverTwo, what you need to do (and this is where it gets fuzzy for me) is to create a subfolder to your app, go to IIS, point to that folder and do a properties on it, then tell IIS that it comes from a share located on another computer (that should be on the first tab of the IIS properties window that comes up). Without doing it myself, I can't recall (and I am at home so I can't try it), but you may have to set up a virtual directory, just don't remember. I THINK that if you go to IIS on serverTwo and setup a virtual directory pointing to the share on serverOne, you don't actually create a real folder on serverTwo (through windows explorer).
But that's the basic idea - you have a folder (virtual or otherwise) on serverTwo that points to the share on serverOne where the text.html resides.
