HTTPS redirect with parameter refresh - El Forum - 07-15-2010

I've recently encountered an issue when redirecting from an HTTPS page with:
Code:
redirect($some_url, 'refresh')I am using the POST/Redirect/GET (PRG) pattern to avoid forms from being posted twice.
A few weeks ago, I noticed that the pattern stopped to work. Even with PRG, pressing refresh or the back button triggered a second form post. It seems to have been caused by the addition of HTTPS.
I found that removing the 'refresh' parameter fixed the problem.
I looked at the definition of the redirect function in url_helper.php and found that the function doesn't treat http and https the same way. Using redirect($some_url, 'refresh') from an http page will simply use the site_url function whereas using it from an https page will call a header("Refresh:0;url=...);
Does anybody know why the function redirect was programmed this way? Why should http and https be treated differently when redirecting?

This is interesting, I'm experiencing this too (still on 1.7.3) and I can't find anything elsewhere about this issue.
