Executing a query
1. The Supervisor executes a query in the Viewer browser window to
display list of Contacts.
2. The HTTP request is executed in the Viewer Server Component.
The Viewer server component executes a Query in the Calls Database.
Selecting a Contact
1. The Supervisor selects a Contact to playback.
2. The Viewer browser executes an HTTP Get of the Contact data on the
Viewer Server component.
The Viewer Server component uses the Locator component to determine
the closest Recorder node to the Viewer browser that can service the
request. This allows the Viewer server to be located in a main office and
the browser and Recorder both in the same branch office. The Viewer
browser will be redirected to the nearby Recorder to service the request
rather than the Contact data being sent to the main office then back to the
local office.
The Locator component redirects the HTTP request to the Recorder
node.
This redirection is passed on to the Viewer browser.
3. The Viewer browser re-requests the Contact from the Recorder.
The Retriever component on the Recorder reads the Contact data from
disk.
4. The Contact data is returned to the Viewer browser.
