Nimbostratusblocking or dropping particular dns requests
I have a request to see if there is a way that we can block or deny requests to www.example.com. but allow example.com. The request is to actually block anything but example.com.

Nimbostratuswhen HTTP_REQUEST {
if { not ([HTTP::host] equals “www.foo.com”)} {
drop
}
}
this iRule checks the host header and drops the request if hostname is not www.foo.com
you can also log, send http redirect, or do anything you want when the hostname is not matching www.foo.com
in case of not well known port number for http:
when HTTP_REQUEST {
if { not ([getfield [HTTP::host] : 1] equals “www.foo.com”)} {
drop
}
}
This iRule returns the hostname without the port number used in request.
