shortcut

I'm not sure if I worded the question correctly to be honest but basically what I want to do is:

When a user types in something like Expenses in the URL bar of a browser, I want the browser to be directed to a specific web address (very very similar to how OpenDNS shortcuts work)

The IP address of the web address will not change amongst the different 'shortcuts'... i.e:

mycompany.com = 10.0.0.0

mycompany.com/expenses = 10.0.0.0

mycompany.com/tracker = 10.0.0.0

When a user types expenses in the browser address bar and presses enter, I want the browser to automatically direct to the specified address as above.

Would this be tricky to implement? I hope I have put my question forward appropriately :-)

Additional notes:

We are on a Windows envionment
I believe the exchange server is running as the DNS server in the office
