hi Alex,
we have lot of servers running for one domain, DNS robin like this:
www.a.com 192.168.11.1
www.a.com 192.168.11.2
www.a.com 192.168.11.3

and all the servers are virtual host, so I can't use 192.168.11.1 to visit the website. how can I know all the www.a.com is ok?

Tongyan:

We have this issue in several places. One very effective way to
solve this is to have a Host Monitor RMA running on the same
physical network as the virtual hosts - that way RMA can use
the real addresses of the host...

192.168.11.1
192.168.11.2
192.168.11.3
...

Then just a single modification to firewall will allow Host Monitor
to speak to RMA Agent. We have a web farm of 60 servers and
another one of 10 servers for which this solution works quite well.

May be Tongyan doesn't have any problems with firewall but his web server returns error when receives URL request with IP address (e.g. http://192.168.11.3/index.htm)?
Do I understand the problem correctly?

Regards
Alex

At our site we have a similar problem. I want to be able to check many virtual hosts on a single ipaddress.

An http 1.1 example conversation looks like this:

telnet [ipnumber] [portnumber]
GET /somefile.html HTTP/1.1 [enter]
Host: myfirstvirtualhost.mysite.com [enter] [enter]

followed by output...preferably '200 OK' ...

Hostmonitor gives you the possibility to send an extra header field. Specifiying a host there doesn't seem to solve our problem

Definitely one for the wishlist...

Probably it doesn't work because HostMonitor always sends standard headers (including 'host:') plus your custom headers.
H'm.. we can make some changes in the code - replace standard headers with your custom parameters (if any)

Wow! Really neat that patch!
It's working great ;c)

Now I can setup individual checks on _all_ virtual hosts.

Thnx a lot Alex
