Get started with block page elements

Custom Block Pages | Web Protection Solutions | v8.5.x | 29-Apr-2022


	Warning Do not edit the default block page files directly. Instead, follow the instructions in Edit block page files (overview) to make a copy of the files as a template for your custom block pages.

The standard block pages included with your web protection solution contain the following elements:

The header explains that the site is blocked.

The top frame contains a block message showing the requested URL and the reason the URL was blocked.

The bottom frame presents any options available to the user, such as the option to go back to the previous page, or to click a Continue or Use Quota Time button to view the site.

When a cloud application is blocked, the block page contains similar elements:

The header explains that the application is blocked.

The top frame contains a block message showing the requested application and the reason the application was blocked.

The bottom frame presents any options available to the user, such as the option to go back to the previous page, or to click a Continue or Use Quota Time button to view the site.

If the site is blocked because it belongs to a category in the Security Risk class, the block page has a special header:

The block page is created from multiple files that are stored with each instance of Filtering Service in your network. This includes V-Series appliances and Windows and Linux servers.

On Windows servers, block pages are found in the following folder:

C:\Program Files\Websense\Web Security\BlockPages\<language_code>\Default

C:\Program Files(x86)\Websense\Web Security\BlockPages\<language_code>\Default

On Linux servers, block pages are found in the following directory:

/opt/Websense/BlockPages/<language_code>/Default

On V Series and X Series appliances, a series of appliance API calls are available for downloading and uploading block page files. See Working with block page files on appliances.

There are 2 primary HTML files used to construct block pages:

master.html constructs the header and top frame for the block page, and uses one of the following files to display appropriate options in the bottom frame


File Name	Contents
blockFrame.html	Text and button (Go Back option) for sites in blocked categories.
continueFrame.html	Text and buttons for sites in categories to which the Confirm action is applied.
quotaFrame.html	Text and buttons for sites in categories to which the Quota action is applied.
moreInfo.html	Content for the page that appears when a user clicks the More information link on the block page.
casbMoreInfo.html	Content for the page that appears when a user clicks the More Information link on the cloud application block page.

block.html contains the text for the top frame of the block message, which explains that access is restricted, lists the requested site, and describes why the site is restricted.

In addition, several supporting files are used to supply the text content, styles, and button functionality used in block pages:

blockStyle.css	Cascading style sheet containing most block page styles
master.css	Cascading style sheet containing styles for block page popups (like the account override popup)
