Standard Mode of Web Filtering

We have been having some minor issues with web pages timing out and having to add a lot of exceptions or bank webpages not working with HTTPS scanning in transparent mode set.

So I have been reading on standard mode as a possibility to solve these problems. In standard mode with https scanning enabled and the astaro firewall as the proxy does the astaro insert itself into the ssl handshaking like in transparent mode?

Also, I was wondering if any applications go through the proxy besides the browsers? We have some systems that authenticate using ssl and we don't really need to go through the proxy server because there is no risk of what they do.

Thanks
