csdn现在怎么这么慢！！！我可是宽带上网，半天打不开一个网页！！！

[maladola]

是的，管理员应该好好地维护维护了。

[everandforever]

我也是!!!

[OakMin]

抗议，我用宽带也这么慢！那56K让人怎么活？？？

[wxdnuaa]

就是，就是

代码摘自Windows Devloper Journal. 不过有许多需要完善的地方,建议你采用WinINET函数,因为它支持HTTPS协议,使用SOCKET也可以实现HTTPS,但是需要更多的编码.另外使用Internet Explorer自动化服务(就象使用Word Excel一样)也可以调用Navigate2发送GET和Post请求.另外一个可取的方案是采用XMLHttp接口的Send方法,该接口MSXML.dll组件实现,利用VC的#import预处理指令,可以简化对XML的操作,使用组件编程可以大大简化你的工作量.
部分代码如下:

[LookSail]

我是ADSL也很慢

[icansaymyabc]

我是50k的，基本上1分钟打开一个网页。
我觉得这跟带宽没关系，是CSDN的人太多了。

[xy328]

不可能比google,sina,sohu人多吧！！！

[syberprince]

快换服务器吧

[dy_paradise]

CSDN要改版了，界面还是差不多， 不过，今天在测试的网站上看看，速度还可以，但我怀疑是不是去的人少的缘故， 如果多了，不知道会怎么样了

[quace]

使用xml，ie的解析速度比较慢
感觉上csdn用了很多华而不实的技术
