the default =2 is set to threading session sharing, that is consider to be better performance, and set to =1 is using the global session pool, that is not that bad unless you can tell that the performance is noticeable, in some case, the global session pool is much safer :D
BTW, that is a problem we should fix, I think TS-1590 as the same type of failure. 在 2013-4-16，下午4:41，오재경 <[email protected]> 写道： > sorry. i forgot to write the title.. > > hi everyone. > > I made a plugin. it calls TSHttpConnect and download a contents when it meets > a range request. as you know, ats doesn't cache partial request. that's why i > made the plugin to trigger full download for a range request. > > proxy.config.http.share_server_sessions makes a problem. default value is 2 > and ATS always crash when the plugin trigger download. > > but with 1, ATS works fine with my plugin. > > i digged the source what happens when i call TSHttpConnect. > > if i set share_server_sessions 2 _acquire_session is called with ethread > parameter. if 1 _acquire_session is called with global bucket. > > my question is ..is it ok if i set share_server_sessions 1 instead of default > value 2 ? > > No problem in performance?
