I have a page that doesn’t always render in Safari. It shows up as a blank page. If I look in the Activity Window, I will see a couple of instances of about:blank in the list of resources being loaded.
Simply refreshing the page fixes the problem.
This can be replicated very reliably, and only affects Safari.
Has anyone seen this before?
SOLVED
Turned out the problem was a control on the page that generated Javascript to create cross-site cookies between two related sites on this project. Safari is very strict in its rejection of attempts to create cross-site cookies, and it appears this is the resulting behaviour.
As soon as I removed the control, the page rendered consistently in Safari.
