Service Caching problem IS 601

Hi guys,
I have this strange problem. I have a service A, which reads properties from a file. This service has Caching setting on. I have a service B, which at the beginning calls service A to get the properties. Service B does not have Caching on. But for some reason the service A Caching affects the service B and some pipeline variables in the service B are also somewhere cached. Does anybody know why is this?
I wanted to use the caching for service A to improve the performance and not to read from file every time the service B executes.

Are there any other approached to reading in configuration data from a file?

Prefetch the server rather than cache the service. You will go crazy otherwise.

Janusz - Clear the pipeline as the first step in your cached service - it will solve the problem.

You see what you see because invoking a cached service restores the pipeline (rather than just the service output variables) of the first run.

IS passes the entire pipeline (instead of just the input variables) when invoking a service, so this behavior can get very dangerous. WM should really document this behavior better.

Thanks guys, this clearPipeline as the first step of the cached service works! And it does not clear the pipeline of the calling service.
Thanks a lot.
