>>In a Web environment, I have 4 VFP servers running to process the incoming requests. I have found that occasionnaly, one save by a VFP server is not reflected immediately on another VFP server. What I mean by that is that it may takes up to two seconds before the other servers can read the updated data from the tables.

SYS(1104) might help also, but usually to assure buffers contain the latest information. Maybe data for another server buffered for certain time so it des not see changes for 2 seconds using cached information. Try SYS(1104) to refresh buffers immediately without waiting for SET REFRESH settings work.
>This also could be a network caching issue, but I do not know exactly.

We do not use buffering.

SET REFRESH is set to default as we didn't change it. So, it should be 0.

It is not a network issue as those 4 servers are running on the data server.

In such environment, are we forced to use SYS(1104) in order to avoid such problem?
