java.net.SocketTimeoutException

[fiooh]

hi to everybody!
I have this problem:

trying to reach some intranet addresses from my webapp, i have to check if a machine is down or not respondig for any other problem, to avoid everything going slow waiting a http standard timeout.

any suggestion?

I'm trying with some classes found on the net: i have not source codes, so i don't know how they works, but the result of a call with my url as parameter is OK or TIMEOUT or ERROR... using standard http addresses, even intranet ones, everything is ok. when i try with the one i'm interested in, i receive this error:

java.net.SocketTimeoutException: Read timed out

the response of the http call is an xml: calling it from ie, everything ok.

any help very very appreciated.

bye

its difficult to guess how they have implemented the code. Typically if you try to access an http address programatically, they you should set the user_agent header in the response so that the destination server knows the request is from a valid browser. Sometimes if its not from a browser the destination server might not respond..
