[Problem]
Use C # To simulate web page login. When several pages are requested, the corresponding HTTP request will be initiated, with keepalive set to true. After the request is submitted, the corresponding response will be generated:
Resp = (httpwebresponse) Req. getresponse ();
After debugging multiple times, you can obtain the corresponding response normally and then read the HTML page.
However,

In the C # simulation page landing, where to request a few pages, will initiate the corresponding HTTP request requests, where KeepAlive is set to true, after the request is submitted, then there will be a corresponding response:

Before the multiple debugging, has been able to get the corresponding response, and then read the HTML page.

The reason for the death of the GetResponse or GetRequestStream timeout may be:
1.DefaultConnectionLimit is the default of 2, and the current HTTP connection is run out, causing subsequent getresponse or GetRequestStream to die
==>> default system only supports 2 HTTP connection
==>>
Symptom
When a page is requestedCodeCode similar to the following:
Httpwebrequest Req = (httpwebrequest) webrequest. Create (strurl );Req. useragent ="Msie6.0";Req. method ="Get";Httpwebresponse res = (httpwebresponse) Req. getresponse ();Streamreader sr =NewStreamreader (res. getresponsestream (), strencode );Strhtml = Sr. readtoend ();Sr. Close ();Res. Close ();
However, if the requested page is a page with an exception or does not exist. The
phenomena
When we encode the implementation request a page, the requested code resembles the following code:
HttpWebRequest req = (HttpWebRequest) webrequest.create (strURL);Req. useragent = "MSIE6.0";Req. method = ' Get ';HttpWebResponse res = (HttpWebResponse) req. GetResponse ();StreamReader sr = new StreamReader (res. GetResponseStream (), Strencode);strHTML = Sr. ReadToEnd ();Sr. Close ();
However, if the page we are requesting is exactly the sa
In HttpWebRequest, GetResponse or GetRequestStream occasionally times out, or some solutions that result from various operation timeouts,
Today, it took nearly one day to find out the problem. Baidu kept searching for the cause of the test and found that the solution was very simple, but it would be better to solve it all, record it here, hoping to help you

Problem Description: Use the request. GetResponse, if it is a 400 error, will throw exception information, and not get the return content, so the returned content can only be obtained on the catch, reproduced inhttp://blog.csdn.net/ahywg/article/details/26267113Workaround: WebRequest request = WebRequest.Create("网址"); Stream stream=null; try { using (WebResponse response = request.GetResponse()) { stream=response.GetResponseStream(); } }

I know it is through the session to judge, that is, after the session through the template how to become a user login information?
Reply to discussion (solution)
User information is fully written to the session template determines whether the user information in the output session or the login box
I usually use the session to judge the corresponding state of the content, if you want to better effect
