Internet Explorer users connecting over dial-up should make sure that their browser is set to use HTTP 1.1 protocol, which allows the browser to read compressed web page content. Because of the size of the Traveler Information Map, it is compressed before it is sent over the web, then decompressed by your browser. To set Internet Explorer to use HTTP 1.1 follow these steps:
1. Under the Tools menu, select Internet Options
2. Go to the Advanced tab.
3. Scroll down to the HTTP 1.1 settings section, and make sure the box next to Use HTTP 1.1 is checked.
