?????? ?????? ?????? why only 2 requests for async request can raise from a end-point?
sorry, it's a .net problem .net - How can I programmatically remove the 2 connection limit in WebClient - Stack Overflow http://stackoverflow.com/questions/866350/how-can-i-programmatically-remove-the-2-connection-limit-in-webclient There is a limit in the number of simultaneous outgoing HTTP connections. I think you can control this by using the System.Net.ServicePointManager.DefaultConnectionLimit static property before creating the HttpWebRequest objects. -- -- ??: ;hsum...@qq.com; : 2015??7??1??(??) 11:42 ??: usersusers@tomcat.apache.org; : ?? ?? ?? why only 2 requests for async request can raise from a end-point?

Hi,
The number of concurrent connections is limited by the browser:

?????? why only 2 requests for async request can raise from a end-point?
Hi,
I wrote a test tool with c#, not with browser, and each request has it's own
session, that browser not support now.
And, PHP and IIS can change option to set the limitation of one end-point
requests, so i can't agree browser has this limit.
I have run tomcat in localhost, and 100 requests are allowed, it's only appear
when the server and client run on different machine.
