I am using indy's http server for a project so i have a few questions: 我正在使用indy的http服务器进行项目，所以我有几个问题：

Does the event OnConnect get's executed even if one connects on a separate thread? 即使一个连接在一个单独的线程上，事件OnConnect也会被执行吗？
Can i update the vcl from the event OnConnect 我可以从事件OnConnect更新vcl吗？
If MaxNumberConnections is set to 0 what does it exactly mean ? 如果MaxNumberConnections设置为0，它究竟意味着什么？

Thanks. 谢谢。

1 个解决方案

1. Does the event OnConnect get's executed in a separate thread ? 1. OnConnect事件是否在单独的线程中执行？

Yes, the event will get fired as the other events do, even if you are running in a separate thread. 是的，即使您在单独的线程中运行，事件也会像其他事件一样被触发。 The question remains to be answered by you is why. 你仍然需要回答这个问题。 The TIdTCPServer already uses multithreading thus TIdTCPServer因此已经使用多线程
it can be used in a main thread context (on a form). 它可以在主线程上下文中使用（在表单上）。

2. Can I update the VCL from the OnConnect event ? 2.我可以从OnConnect事件更新VCL吗？

Yes, but you will have to use some GUI synchronization practice, such as Synchronize method or eg message posting from the separated worker thread to your main one. 是的，但您必须使用一些GUI同步实践，例如Synchronize方法或例如从分离的工作线程到主要工作线程的消息发布。

3. If MaxNumberConnections is set to 0 what does it exactly mean ? 3.如果MaxNumberConnections设置为0，它究竟意味着什么？

Zero value assigned to the MaxConnections means there is no limit of connections at one time. 分配给MaxConnections零值意味着一次没有连接限制。
