@brief interface for throttling of connection (count and rate-limit speed etc)
|
|
@details <PRE>
|
|
|
|
Throttling work by:
|
|
1) taking note of all traffic (hooks added e.g. to connection class) and measuring speed
|
|
2) depending on that information we sleep before sending out data (or send smaller portions of data)
|
|
3) depending on the information we can also sleep before sending requests or ask for smaller sets of data to download
|
|
|
|
