Refreshing updated content

Some Web sites, especially those that cover current affairs or the news, frequently update the content of some or all of their pages. If your purpose in capturing Web pages is to keep up-to-date on the information offered by a site, you will need to refresh the pages on a regular basis to ensure that your file has the most recent content.
To refresh the content of the captured pages in your PDF file, choose Advanced➪Web Capture➪Refresh Pages. Doing this opens the Refresh Pages dialog box. Click the Refresh button to have Acrobat check all the pages in the Refresh Commands list for updates. By default, the program compares the text of the captured pages with their counterparts online. If Acrobat detects any discrepancies between the two, it automatically updates the downloaded page in the PDF file by replacing it with a copy of the latest page on the Web site. If you want Acrobat to compare all elements on the Web pages when looking for the ones that need refreshing instead of just comparing the text, select the Compare All Page Components to Detect Changed Pages radio button in the Refresh Pages dialog box before you click the Refresh button.
If you want to exclude certain pages from the Refresh Command list, click the Edit Refresh Commands List button to open the Refresh Commands List dialog box. This dialog box lists all the pages marked for refreshing. To skip particular pages in the refresh operation, click the Clear All button and then select the URLs for all the pages you do want refreshed to highlight them before you click OK.
Keep in mind that you can’t add new URLs to the list displayed in the Refresh Commands List dialog box: You can only tell Acrobat which ones to ignore when refreshing the pages. The only way to add a URL to the Refresh Commands list is to capture its Web page when the Save Refresh Commands check box option has been checked in the Web Page Conversion Settings dialog box.
