RE: Setting timeout in HttpURLConnection

Dear Mr. Lazar,

1.)	According to the Java SE v1.3 API, Socket.setSoTimeOut(int timeout) must 
be called before that Socket is blocked for the method to have an unblocking 
effect.

2.) 	So, if you are trying to unblocked a Socket by changing its timeout 
value, I think that you are going to have find a new approach.

3.)	Frankly, I think that you should edit the HttpBasicConnection file and 
change the default value of "timeout" from 300000 to something like 30000.  
This way you can get to the heart of the matter quickly  (ripping through 
all the various levels of architecture) and hopefully ascertain that you are 
indeed on the right path.  However, I have done this myself and it did NOT 
appear to solve my problem (which appears to be similar to yours).

4.) 	Now, I am trying to write code that implements something like 
HttpManager.setRequestTimeout(int ms).

Keep posting.
