Difference Between Block-Continue and Continue in URL Filtering Logs

Block-continue appears in the logs for the first URL that matches a category where the policy requires the user to click the continue button after being presented with the warning page.

After the user has clicked continue for a category, the logs for that category will show "continue" for the rest of the requests up until the point where the timeout has been reached. When the timeout is reached, the user will be presented with a new warning page and must click Continue again to proceed.

This timeout is configured on the Device > Setup > Content-ID tab.
