Three methods for redirecting from an asp.net page

　　Currently. net many students are not very clear about several methods of asp.net page Jump. Understanding the three methods of asp.net page Jump will be of great help for future programming. Let's take a look at the following:

1,Response. redirectThe method used to jump to the page is not fast because it takes two rounds (two postback), but it can jump to any page, there is no website page restriction (that is, you can jump from Yahoo to Sina), and you cannot skip logon protection. However, slow speed is the biggest defect! Redirect jump mechanism: First, send an http request to the client. The notification needs to jump to a new page, and then the client sends a jump request to the server. It should be noted that after the jump, all the data information stored in the internal space will be lost, so the session needs to be used.

2,Server. transferFast, only one postback is required, but it must be in the same site because it is a server method. In addition, he can skip logon protection. You can try to write a small program: design a jump from page 1 to page 2, but to enter page 2, You need to log on and perform form authentication. However, if the jump statement uses transfer, the logon page will not pop up. The redirection request of this method occurs on the server, so the url address of the browser still retains the address of the original page!

3,Sever.exe cuteThis method is mainly used in the page design, and it must jump to the page under the same site. This method needs to be used to insert the output results of a page to another aspx page. Most of them are in the table, where a page is nested to another page.

　　Summary:

When you need to redirect a user to a page on another server, use redirect

When you need to redirect a user to a non-aspx page, such as html, use redirect

When the query string needs to be retained to the server as part of the url, because the other two methods cannot achieve two postback operations, the data is first brought back to the server, and the redirect

Switch between aspx pages (logon not involved), use transfer

Execute is used to insert the output result of the aspx page to another aspx page.

Of course, I forgot another hyperlink! Of course, you don't need to talk too much about this. He uses hyperlinks when a user needs to decide when to jump to a page.

The above three methods are introduced to jump to pages in asp.net. The implementation methods of each clock are different. I hope you can understand and skillfully use each method.
