Difference between "HTTP" and "HTTP Full Web Page" web server sensors
The HTTP Full Web Page sensor uses a web browser instance to fully load an entire web page (including all embedded objects such as images) and monitors the loading time.
Note: This sensor does not monitor if all embedded objects can be loaded.
The HTTP sensor performs specific HTTP requests. When it is used in GET mode, for example, it merely loads the HTML code of a web page, not the embedded objects.
