What is an ecv check?
ECV stands for "Extended Content Verification".
An ECV check is typically used to verify a computer server is
functioning properly.
It usually works by making an HTTP call to a specific web page.
It will then examine the returned HTML and verify the content by
looking for a keyword (or expression).
Only if the page is returned (within a certain timeout) and
contains the keyword, will the check be considered successful.
For example:
ECV Check: http://myserver.mydomain.com/admin/check_ecv.jsp
Keyword: "server_okay"
Many organisations use additional logic that allows them to take
servers in and out of service for maintenance, upgrades, etc.
This logic can control the content of the "check_ecv.jsp" page
accordingly.
