Precision about cache_views and cache_views_data

Hi, i was asking myself how views cache handle a same view called with different arguments.

Does it create one cache per view and for each different argument value passed ?
I guess maybe it's the difference between cache_views and cache_views_data...

I saw that cache_views_data has a cid field that contains the name of the views and a md5() hash, is it the md5 of the mysql request so that it handles a cache entry per argument value passed ?

Thanks in advance for this info, and thanks for this great swissknife module
