    What happens to data when a page errors

    I am a newbie on this site and new to technology.

    Are there any security concerns when you enter in confidential information such as credit card number on a website and you get an error. What happens to the data.

    Thanks,
    Cassandra

    It depends what causes the error. Hopefully you're using Secure Sockets Layer (SSL) anytime you ask the user to provide confidential information. SSL encrypts the data between the user's browser and the Web server. So if the error happens before the data leaves the user's computer (for example, the user's browser cannot connect to the Web server), the confidential data has not gone anywhere; it's sitting in memory or on disk on the user's PC. If the data makes it to the Web server and then the Web application has an error, the data is sitting in memory or on disk on the Web server. If an error happens between the time that the data leaves the user's PC and before it reaches the Web server, it's encrypted so no one can read it.

    Nowadays, every user of a public network sends various types of data, from email to credit card details daily, and he would therefore like them to be protected when in transit over a public network. To this end, a practical SSL protocol has been adopted for protection of data in transit that encompasses all network services that use TCP/IP to support typical application tasks of communication between servers and clients.

    And this is a very good thing providing the site in question has a SSL layer.

    I am very, very particular about what sites I use credit cards on.
