About enabling and disabling the AutoRepublish feature

Each time you save your workbook, you can automatically republish it to the Web. Check the AutoRepublish every time this workbook is saved box in the Publish as Web Page dialog box.

There may be times when you don't want to automatically republish items in your workbook. Examples follow:

When you have entered confidential or sensitive information that should not be published to a public location
When you're temporarily disconnected from a network or Web server location
When you're saving a workbook that was created by someone who is not a trusted source (the workbook could contain macros that collect information from a network location using your credentials, and then publish that information to a public location)

You can disable AutoRepublish temporarily (for the current open and close session) or permanently (every time you open, save and close). Or you can continue to AutoRepublish.
