Form Re-Submission Errors & PRG Patterns

[afcouling]

Although I should know better, it does annoy me when I get the form re-submission error alert, after clicking on the browser back button.

Has anyone considered implementing the 'PRG Pattern' (Post/Redirect/Get), to reduce the likelihood of the above occurring?

I found this relevant article on form processing.

Are there any views on the benefits, drawbacks, and difficulty of implementation?
