If I understand you correctly, when I give the HTTPURITYPE.createuri command, I am in essence telling Oracle Net to make an outbound HTTP connection. I'll buy that, but there is still something I don't understand which is ...

why is it taking about 4 minutes to time out and what can I do to shorten the length of time. We need to have the timeout happen in about 5 seconds. Basically, if the Apache server is not reachable, wait 5 seconds, log the error, and move on. I thought that UTL_HTTP.set_transfer_timeout (5); would do that for me, but my experience shows me that it only works sometimes.

My GUESS is that it goes like this:

If connection to target server succeds, but target server does not reply THEN

      wait UTL_HTTP.set_transfer_timeout (5); and raise UTL_HTTP error ELSIF

     connection does not succeed (i e. cant even find the server)
          wait some TNS defined interval and raise TNS time out error;

If my above GUESS is true, then how can I make the TNS outbound HTTP connection time our more quickly?
