Re: HTTP API or Web Service concurrency issue

Mike,

If it helps, you can add code like this to the start of your RPG code:

http_debug(*on: '/path/to/ifs-log-file.txt');

This will log exactly what HTTPAPI does to the specified file. If the data is mixed-up in HTTPAPI, you'll be able to see the mixed up data in that file.  If the data in the log file is good, but it's mixed up on the server, you'll know the issue is happening on the server side.

Hi Nathan,

I agree. My first suspicion is the web service / server is the most likely
culprit. That team seemed to quickly rule it out, but we all don't want to
believe our code has issues, even when history has proven us all wrong
repeatedly. I suspect I'll be circling back to them very soon.

Mike,

I'd recommend that you look deeper at the web-service server. In regard to
a problem where one client receives the result intended for a different
client, that is much more often a server issue, rather than a web-service
client issue.

We're using the HTTP API plus internal web services and are occasionally
experiencing a concurrency issue, where the results of one web service

call

are getting mixed up with the results of a different web service call.

RPG <--> HTTP API <--> Java Web Service

Our RPG and Java teams don't think the problem is in their code (of

course,

which I don't necessarily believe). But, they asked me to look into if
there have ever been concurrency issues in the HTTP API product by Scott
K. Has anyone seen any concurrency issues like that?
