How should I choose between GET and POST methods in HTML forms?

Question

I wish to know all the pros and cons about using these two methods. In particular the implications on web security.

Thanks.

Answer 1

GET should not have side-effects: http://www.w3.org/DesignIssues/Axioms.html#state

POST forms should be used when a submission has side effects.

Neither method has any real implication on security, use SSL if you're concerned about security.
