How can you set Safari to warn you each time you access an insecure wireless connection?

The first time you access an insecure internet connection, Safari warns you, but I can't figure out how to set up a warning for subsequent time. I travel to Chicago pretty often, and there are a networks that I use with my iPad (sometimes at Starbucks, I hang my head and admit). I have had a couple of times when "Free Wi-Fi" popped up at places I know good and darn well there is no free Wi-Fi, so my assumption is that someone is trolling for a connection to hijack. A little later, I came back to the same location, and there was no warning even though the same "Free Wi-Fi" was still there. I'm usually pretty careful, but I worry about not noticing sometime when I've got something on my mind. I can't figure out how to change settings so that the same unsecured connection generates a security certificate warning on subsequent occasions. Is there a way to change this?

The problem is that even if you go through a secure network connection (SSL or TSL), you can still be using a insecure WiFi connection.  If I was a black hat kind of guy, I would set up an open WiFi in the same area as a coffee shop or some other place that traditionally has free WiFi and sit back and sip my espresso while I intercept your data.  The way Safari warns you about the insecure WiFi connection, you only get a single security certificate warning for THAT connection.  So if you come to the same coffee shop in the morning and afternoon, you will be warned in the morning, but I would have a good chance of snagging you in the afternoon if you weren't paying attention.  Sorry to tell you this, but as far as I know, you can't adjust the settings in IOS or Safari to warn you each time.  I would set a mental red flag every place I saw a WiFi with a name like "Free WiFi" and avoid it like the plague unless I was absolutely certain it was legit.  Even then, I would avoid it like the common cold, but I'm a little paranoid.

Here's what Apple has to say about identifying secure sites in Safari:

Safari 5.1 (OS X Lion): Identify secure websites
http://support.apple.com/kb/PH5018

"When you use a website that handles private or financial information, make sure the website is secure.

Look for a lock icon
A lock icon at the top of the Safari window or in the address field means that the website has a certificate. This indicates to Safari that it’s a legitimate website and that information you exchange with it will be encrypted.

To view the contents of a website’s certificate, click the lock icon.

For more information about certificates, see:

Certificates and secure websites

Check the address
Make sure the website’s address begins with “https” (instead of “http”).

Use a secure connection, if available
If the website is not secure, you may have been given a choice between a secure and an insecure connection when logging in to the site. Go back to the page where you logged in and check for a link to a secure login. Even if you don’t plan to view private information, it’s best to use a secure login whenever possible to ensure that your login information and any other information you send is encrypted."
