* we | * we probably want to require a client string and client version in every query (similar to udp api) to be able to ban badly broken clients, should the need arrise someday. | ||
=== Protocol Draft === | === Protocol Draft === | ||
Every query should contain as additional paramets: | |||
* client={str client name}&clientver={int client version} | |||

** load factor: a simply multiplicative constant which is used to distinguish between fast and slow server hardware. This can i.e. be used to store twice as many fingerprints on one server compared to others. The fingerprint count is converted according to the following formula prior to comparison/selection of least used server. | |||
*** relative fingerprint number/load = number of fingerprints in db * (load factor / 100) | |||
(might be extended with additional data someday, i.e. real average foosic load) | |||
