HttpResponse body is being altered

Question

We are facing a peculiar issue at the moment and we have no clue what is causing this.

We have a web-service hosted on serverA. When this web-service is invoked from serverB (using the command, curl http://serverA:8008/service/getId), we get the required response. (the web service returns an Id which is an integer).

When the same web-service is invoked from serverC, we get the required response but the digit 2 in the response is getting replaced by _ .

For example, we get 5002 when the web-service is invoked from serverB. When the same web service is invoked from serverC, we get 500_

We checked the wireshark details from serverA and the data going out from serverA is the same for both the servers.

We have no clue at the moment why this is happening. I would like to add that serverC is in DMZ while serverB is not.

Any input/help in this regard is highly appreciated.

Answer 1

by gather the facts that

 1. Server doesn't change the response by its own.
 2. Web Service is giving the same response for the same input.

only culprit is your firewall, can you stop it for testing purpose and see if the response is coming as expected. OR Try to check the firewall settings and create a hole/exception for web Service.
