Additional Information
The various symptoms needing Webview cache cleared and related knowledge documents are the following:
Issue #1: While connecting to a Webview server (http://<APM WebviewServer_Hostname>:8080, by default) through a browser as a Webview client, there is an issue rendering images
Issue #2: After modifying the default WebView listening port value for the property "introscope.webview.tcp.port" in the IntroscopeWebView.properties file, the new WebView URL (http://<hostname>:<port>) fails with error "HTTP ERROR 500".
Issue #3a: After upgrading from 9.x to 10.x and using the Webview interface, the dashboard dropdown list on the console tab does not work. When clicking a dashboard in the dropdown, the new dashboard does not load. Also, links on dashboards do not work.
Issue #3b After upgrading from 9.x to 10.x and using the Webview interface, the dashboard dropdown list on the console tab does not work. When clicking a dashboard in the dropdown, the new dashboard does not load. Also, links on dashboards do not work.
Issue #4: My dashboards has alerts that are linked to other dashboards. In the WebView Console, when clicking on an alert to go to another Dashboard, instead of seeing that Dashboard, I am brought to the Dashboard named "Welcome to APM Dashboards". This does not happen in Workstation.
Issue #5: Renaming of Management Modules cause dashboard links to fail in WebView
When Management Modules are renamed, dashboards containing links referring to other dashboards will not work on the fly in WebView unlike Workstation.
