Submit Design Question

[gd...@cmhc-schl.gc.ca]

Hi,

I have an application that permits a user to view and update Contact 
information.
/app/Contact (gets data from the DB) --> posts to --> /app/ContactSubmit 
(updates the data after validation)

I would like to ensure that the application is solid and executes smoothly 
(doesn't eveyone!). ;>

Question 1:
-----------------
Is the above process a valid one?
Or should the GET and POST be done with the same URI such as 
(/app/Contact).

Question 2:
----------------
I would like to prevent any processing or errors if someone enters the 
/app/ContactSubmit URI in a browser address.
One way to do so is the check the HTTP request for a GET in the Action 
class... and if found show an error page...
Any other suggestions?

TIA,
Glenn.
