I'm working with our network team to configure layer 7 healthchecking for a WAS 6.1 system.
We're proving the connection in a similar manner to how the device will check it, by opening a telnet on the correct IP and port and then issuing a GET request e.g.
When used with IIS the server handles this and responds with a 200
When used with the WAS 6.1 system, the server responds with a 505 unknown protocol.
If I add the HTTP version to the request it completes correctly e.g.
GET /path/index.html HTTP/1.1
however this seems to cause other problems for the network team so I'm trying to understand why WAS responds in this manner compared with other web-servers
