I have two virtual directores for my website. One directory is for "testing" and the other is production. On both websites, the main page navigation defaults to a default.aspx page.
On my testing site, the page comes up fine, but on my production site, users get a warning that they are about to view mixed content (both non ssl and ssl)
That use to pop up because something in the code referenced a non ssl location, but now, both pages have the exact same code.
So why would one site cause Internet Explorer users to get the warning about mixed content, when the other site does not cause that and they both have the same code?
