i have one strange response problem with my VB.NET web service (ASMX) hosted in Win 2008 server (IIS 7).
The win server is connected via VPN and firewall to get access. I've hosted our web service in IIS and while trying to access it from the other end, we have constantly getting 15 seconds delay on the response.
The request (ssl secured request is made) is reaching the IIS and then the 15 seconds delay is occurring then the request reaching the service and immediately (~40milliseconds) the response is returned. so totally the response is going after ~15.40 seconds.
Why is the 15 seconds delay is occurring before each response? what do i need to check for this?
since our test server returns the response immediately (~40ms) which is public and not having external firewall.
while checking the packets traffic using WireShark application, we found the request is reaching the IIS and then there is 15 seconds delay before the response.
Can anyone provide a solution or suggestions that would be appreciate a lot.
