Does anyone know of any addons to nginx that would let it do content
checks to determine if an upstream server is alive or not, i.e. check a
certain page for a given string?
We are hoping to replace a lot of old ldirectord load balancers but this
is a feature we really need to have. All too often a web server (cough
cough IIS) will be responding to connections but giving errors instead
of showing valid content (cough cough ASP.NET), but by doing a content
check the load balancer will take the broken server out of the farm.
