Alert/Actions on

 

With the "Alert/Actions on" option you can define when an update notification and bookmark actions (eg. "Send e-mail") should be performed. Default value is "Alert-On-Changes", that means that you get only update notifications when a page is changed.

 

See also "Alert with the first initialization of a page" and global error handling in the program configuration.

Technology to check web pages

Internal

This is the default method to check pages. You should only try alternative methods if this method fails.

 

Browser

Use this method if WebSite-Watcher cannot check a page with the internal check technology, for example when a web page can only be displayed with Javascript.

By default, WebSite-Watcher filters all Javascript content from a page and works only with the static, textual content. This technology opens the page in a hidden browser window and converts the "dynamic Javascript content" to a static, textual content that can be used and processed by WebSite-Watcher. Supported browser engines are Chromium, Edge and Internet Explorer.

 

Delay after page has loaded (in seconds):

This option must be used for pages which change the content dynamically after the page has loaded. For example when it takes a few seconds until the final content is displayed.

 

Scroll pages down:

Number of pages that should be scrolled down during a check. Use this option if a page displays information dynamically when the page is scrolled down.

 

Alternative method to get page content:

This method analyzes all transferred documents and collects them to a single page. This method might be useful if WebSite-Watcher cannot resolve IFRAMES or other embedded elements. There are different methods that can be used on a try-and-decide basis.

 

Screenshot

If a page contains content that cannot be monitored with the other methods (eg. content that is displayed with Javascript), you can try to create a screenshot of that page and compare that screenshot to detect changes. See chapter Check by screenshot for more information. Supported browser engines are Chromium and Edge.
