How to close the direct path to the controllers in ZF1?
This is necessary because I have one entry point through pageAction where checks are made, then sent to the desired action through forward. So I don’t want to do checks once again, and if I don’t do them, there is a chance that the user will write something like default/site/page/idChecked/bad_id - for example, not a numeric value.
