When Webroot cloud lookup is enabled and a URL that can not be categorized using the local Webroot database managed on the BIG-IP system, the Webroot cloud database look up is performed in a way that the entire URL is considered as one query rather than by its subparts.
Potential performance impact due to additional, unnecessary Webroot cloud lookup. This only occurs when Webroot cloud lookup enabled. The Webroot cloud lookup features is disabled by default.
If Webroot cloud lookup is enabled, and if the first request is: example.com/url1 and second request is example.com/url2, the second URL request results in an unnecessary cloud lookup.
The issue has been addressed with granular Webroot cloud lookup so that the 1st URL Webroot cloud lookup request gets all cloud results, so that additional Webroot cloud lookups could be avoided.
