Asp.net page calls redirect, execute, transfer

Use redirect to redirect a user to a page on another server.

When you need to redirect a user to a non-aspx page, for example, html uses redirect

The query string must be part of the url

1 response. the redirect method does not jump quickly 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 data information stored in the internal space will be lost, so session is required.

2 server. transfer is fast, only one postback is required, .... It must be on 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 cute this method is mainly used in the page design, and he 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.

　　
When it is retained to the server, because the other two methods cannot be postback twice, the data is first brought back to the server using redirect

Switch between aspx pages (logon not involved) Using 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 the party needs users to decide when to jump to the page.

By the way, how to use the redirect method to use Chinese Characters in query strings is often garbled because URLs do not support Chinese characters. In this case, the conversion is required:

String message = server. urlencode ("welcome to the racing column ");

Convert the query string first.

Response. redirect ("webform2.aspx? Msg = "+ message );
