dp:url-open's timeout value is getting ignored in datapower

Question

I am providing a timeout of one second , however when the URL is down it is taking 120+ seconds for the response to come. Is there some variable or something that overrides the timeout in do:url-open ?

Update: I was calling the dp:url-open on request-transformation as well as on response-transformation. So the overriden timeout is 60 sec, adding both side it was becoming 120 sec.

Here's how I am calling this (I am storing the time before and after dp:url-open calls, and then returning them in the response):

Case 1: When the url is reachable I am getting a result like:

Case 2: When url is not reachable:

Update: FIXED: It seems the port that I was using was getting timed-out in the firewall first there it used to spend 1 minute. I was earlier trying to hit an application running on port 8077, later I changed that to 8088, And I started seeing the same timeout that I was passing.

The do:url-open() timeout only affects the operation done in the script but not the service itself. It depends on how you have built the solution but the time-out from the do:url-open() should be honored. You can check this by setting logs to debug and adding a <xsl:message>Before url-open</xsl:message> and one after to see in the log if it is your url-open call or teh service that waits 120+ sec.

If it is the url-open you have most likely some error in the script and if it is the service that halts the response you need to return from the script (or throw an error depending on your needs) to halt the service.

You can set the time-out for the service itself or set a time-out in the User Agent for the specific URL you are calling as well. Please note that the time-out will terminate the service after that time if you set it on service level so 1 sec. would not be recommended!
