Why does the McGraw-Hill Professional web site use cookies?
On our site, session cookies are used for our online ordering system. In this instance cookies remember what a customer wants to buy by keeping track of items placed in the user’s shopping basket. If the shopper were interrupted while shopping, the cookie file would contain/record the contents of their shopping basket until they returned to continue shopping. Some cookies have expiration dates. When a cookie expires, your browser will simply erase it from your hard drive. Temporary cookies will only remain active while your browser remains open. Once the browser window is closed, the cookie will expire and be erased from your hard drive and subsequently you would lose the contents of your shopping basket. This is commonly known as a “session cookie”.
