Is there a limit on the number of concurrent HttpWebRequests.NET allowing at one time?
I'm not sure about the general limit, but, of course, there is a limit on the number of simultaneous connections to a single host name.
It can be configured in the <connectionManagement>app.config file element .
<connectionManagement>
, config. , ServicePoint.ConnectionLimit ServicePoint ServicePointManager.DefaultConnectionLimit ( , ). - 2 (DefaultPersistentConnectionLimit )
