HTTPS seems to redirect to HTTP after editting a wiki page

[chris@…]

I've got Trac running under HTTP on port 445 (yes non-standard port). It all seems to work beautifully from what I've tested except when I edit a wiki page. I make the edit, then click the Save button and I appear at a 404 page because Trac has redirected to a HTTP protocol not HTTPS. When changing the HTTP:// to a HTTPS:// I do see my changes however. Is this something I've set up wrongly or is it a Trac bug?

Regards,

Chris

Apologies, see #3208.

SetEnv HTTPS 1

It's because I'm running over CGI I think.
