You can specify a document footer, which can include the last-modified time, for all the documents in a certain section of your server without using server-parsed HTML. This footer works for all files except the output of CGI scripts or parsed HTML (.SHTML) files.
HINT: If you need your document footer to appear on CGI-script output or parsed HTML files, enter your footer text into a separate file and add a line of code or include another server-side to append that file to the page's output.
Click Enterprise Web Server servername > Content Management > Document Footer.
Select the resource that you want to apply the document footer to from the Editing drop-down list.
Click Browse to view the different server resources.
To enter the pattern you want to edit, click Wildcard .
In the For Files of Type field, enter the kind of files that you want to include in the footer. The default is text/html.
Select the time format from the drop-down list or enter a date in the Custom Date Format field.
In the Footer Text field, enter the footer text.
The maximum number of characters for a document footer is 765. Type the string :LASTMOD: if you want to include the date the document was last modified.
Click OK > Save and Apply.
To change the footer text, click Deactivate Custom Trailer.
When you change the document footer for an HTML page, the last-modified date doesn't change.
