Problem Cause
For STOREFRONT type monitors, ADC will send two http requests (GET /Citrix/Roaming/accounts and GET /Citrix/Store/discovery) to the storefront server, when both http responses returned by storefront server are 200 OK, ADC will consider the monitor result as successful.
In customer's environment, the http response for request GET /Citrix/Store/discovery is 404 Not Found, so ADC will consider the monitor result as failure.
