Yes, I do have a ticket open.
I was testing yesterday and found that when browsing to HTTP://MSN.CO.UK which should redirect to HTTPS://WWW.MSN.COM/EN-GB there is often a problem. It’s not always the Google 404 sometimes the page doesn’t load or sometimes it produces an error on the website.
This doesn’t happen with Google Chrome at all.
I realise that this suggests the problem lies with IE but this is what our company & many others use by default. I have also tested on my home PC and got similar issues (not Google 404 but pages not loading).
I like the fact that the ZIA with tunnel mode enable captures traffic from applications that aren’t proxy aware and makes them work but at the moment it looks like we are going to have to avoid using this as it’s causing too many problems.
Could you replicating this and let me know how it behaves (I assume based on your previous post it’ll be fine but it’d be a useful information) you might need to load it a few times and possibly try from an private browsing window.
To me this seems to be a ZS issue but I don’t think they want to accept that at the moment.
I’ve replicated on 3 different builds of Windows with one of those being a non-corporate build.
