I am developing a tool to print PHP debug messages on screen.
I would like to stop the
wp_redirect() function from actually doing the redirect if the debug tool contains a message that it wants to display.
One way would be to check this before calling
wp_redirect() at all, but it's preferable to have something like a
before_redirect filter where I can decide to "go on" or "don't go".
I have seen the
wp_redirect filter allows me to filter the redirect location.
I could say "go back to the same place" but that would be a new http request and the logs would be already lost.
