getresponse alternatives

Word, tool update-alternatives is the function of the management system under the similar function of the symbolic link, the way is to have a similar function of the program, not directly call the program, but with a unified symbolic link to call, as to the symbolic linkWhich of the similar function programs is pointed to, is configured and managed by the tool update-alternatives.It's very abstract, so let's take an example and see what's going on nat

Update-alternatives is a tool dedicated to maintaining system command links in Linux systems, which makes it easy to set which command to use by default, which software version, for example, we have both open jdk and Sun JDK Two versions installed in the system. And we want the system to use the sun JDK by default, what should we do? Through the update-alternatives can be very convenient to achieve.To view

Alternatives and update-alternatives seem to be the same tool (different for each Linux distribution), so here's an example of update-alternatives. Update-alternatives is a very useful tool in Linux, not only in the Debian series, but also in the Redhat series.Linux has grown to today, and there are so many available s

[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, the subsequent debugging has not changed.Cod

Transfer from http://www.crifan.com/fixed_problem_sometime_httpwebrequest_getresponse_timeout/comment-page-1/#comment-436221 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 payload = System.Text.Encoding.UTF8.GetBytes(postDataStr); request.ContentLengt

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(); } }

Alternatives is an important version management tool under UNIX, which was first seen in the Debain system, because its powerful usability makes it a large number of porting in various UNIX environments, And we probably most often use the Java OPENJDK Toolkit in the usual version of the conversion, and in the alternatives implementation of multi-version is the replacement system using the command link to im

Alternatives command usage Alternatives is a powerful command in Linux. It can only run under the root permission. If the system has several commands with similar functions but cannot be deleted at will, you can use alternatives to specify a global setting.Alternatives is often used to install multiple versions of the same software on the same system. For example
