NSURLConnection和keep-alive [英] NSURLConnection and keep-alive

问题描述

我在使用NSURLConnection的客户端应用程序中有一个小错误。我已经跟踪到一个意外的连接保持活动，似乎混淆了Web服务器（可能是服务器端的一个错误）。解决方法是在某一点强制关闭所有未完成的连接。我可以通过NSURLConnection，也就是像


[NSURLConnection closeAllIdleConnections]


解决方案

ASIHTTPRequest 有一个expirePersistentConnections方法。它可以做你想要的东西。

这不是NSURLConnection的替代，但是将代码从NSURLConnection移植到ASIHTTPRequest并不难。 p>

I have a small bug in my client app that uses NSURLConnection. I have tracked it down to an unexpected connection keep-alive that seems to confuse the web server (probably a bug on the server side). The workaround would be to force-close all outstanding connections at a certain point. Can I do this somehow with NSURLConnection, i.e. something like

[NSURLConnection closeAllIdleConnections];

解决方案

ASIHTTPRequest has an expirePersistentConnections method. It may do what you're looking for.

It's not a drop-in replacement for NSURLConnection, but it's not too hard to port code from NSURLConnection to ASIHTTPRequest.
