synchronizing non-static between fan server


say i've got client-side opposing variable. i send ask server, i send variable's value, following increment (for unbroken ask server). server keeps lane opposing independantly, checks certain count sent fan 1 some-more it's possess (server-side) duplicate count. glorious dandy, nonetheless cruise following situation:




  1. the fan sends, say, 23 server.

  2. the server receives 23, validates it, increments the possess opposing 23.

  3. the server advantage all-okay formula client



-but-



along proceed server client, relapse formula gets corrupted. fan so thinks server transform the counter, leaves client-side opposing during 23. indicate onwards, fan server out sync.



does anybody know any strong schemes work face such illusory corruption/errors?



thanks,

cameron
