Is it okay to leave a controller without a view?

[eluser]rvillalon[/eluser]
I have a controller for error logging and is accessible by the browser. For example, I can access it and log an error by going to:

http://www.mywebsite.com/error/save/acce...tl_details

The last three parameters are used as follows:
access_key : i match this in my config file to make thwart unwanted requests
error_id : unique id to store
addtl_details : additional error description

Once it validates the information, I save into a database but I don't have any "VIEW" set up. It simply returns a blank page.

Is this okay?

Also, does anyone have any tips on how I might improve this?
