I notice that resource validation works on some servers but not others; in other words http://www.server1.com/index.htm will show up as existing but http://www.server2.com/index.htm does not. Presumably this is due to server 2 blocking the ping or whatever it is that phpstorm sends out to validate the file. Could someone give me a clue about how I get server2 to respond properly to phpstorm? I'm guessing it's some sort of firewall/port issue.
Validation of web links blocked by some servers?
