I was on YAHOO and I typed in a search name. Soon it comes back with the results and I noticed that it has changed its URL toi somethign else with my search pattern in it:
Originally the screen was your usual text input box form. It submits the entered text to: http://search.yahoo.com/bin/search
How did it wind up "adding": ?p=halle+berry if I originally called the search engine without it? Did it possibly "recall" itself with a LOCATION http header command in CGI and added the query string data?!
And if they're using the LOCATION command, I thought it isn't 100% perfect meaning not all browsers can support it? Wouldn't it be very risky for YAHOO...
