If the client machine is blocked by Web Client Blocking, the Customize
Response screen will not appear.
To customize the response using the Web interface:
1 Click Content Filter on the Toolbar.
2 Select Webcache Filtering > Custom Response in the Navigation Tree.
3 Enter up to 512 characters of text or HTML code in the Add This Text field
that you want to add to the response screen that informs the end user
that access has been denied. The text or HTML that you enter will be
appended to the standard text that appears, which is "You are not
authorized to view this page". You cannot change or delete this standard
text.
You cannot add images to the Customize Response screen e.g. gif or jpg
files.
4 If you want to view your changes before saving them to check that your
text or HTML is correct, click Preview.
5 Click OK to save the text or HTML code that you have entered.
There is a default option in Microsoft Internet Explorer 4 and later
versions that will cause a "friendly HTTP error message" to be displayed
when a Web site is blocked, rather than the response page generated by
the Webcache. You can turn this setting off from Internet Explorer by
selecting Tools > Internet Options > Advanced and unchecking Show
friendly HTTP error messages. The response page generated by the
Webcache will never be displayed by Internet Explorer if you do not
change this setting.
For a description of the use of friendly HTTP-status error messages, view
