asp.net-mvc – 在ASP.NET MVC3中有一个无会话控制器的情况是什么？

读 Guru-Gu’s blog post about ASP.NET MVC3 hitting RC他说：

Session-less Controller Support

You can now indicate whether you want a
Controller class to use session-state
– and if so whether you want it to be
read/write or readonly.read/write or readonly.

有人可以解释一些情景有人想要拥有无会话控制器吗？或只读控制器？

我一直在创造一个separate IIS website which I use to handle all static images/content and then have this same website have session state turned off …所以没有饼干通过电线发送。这是一个类似的场景吗？

解决方法

The release notes cover this more (you
can download them from the download
link above). Session state is
designed so that only one request from
a particular user/session occurs at a
time. So if you have a page that has
multiple AJAX callbacks happening at
once they will be processed in serial
fashion on the server. Going
session-less means that they would
execute in parallel.

这是ASP.NET中一个已知的场景。同一用户的会话对象不是线程安全的。这意味着如果同一个用户(相同的会话id cookie)向使用会话的页面发送多个请求，那么这些请求将被排队并且将被并行处理，而不是并行处理。
