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 the data information stored in the internal space will be lost, so the session needs to be used.

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.

Summary:

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

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 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 );

Comparison of Asp.net methods for redirecting from one page to another

There are many ways to achieve page Jump, except that the server control is encapsulated by Asp.net, other methods are available in ASP.
In so many implementation methods, the same function is implemented. Why do we need to support so many methods? Our actual application
Which method should be selected? Maybe most of us need to jump and use it whenever we think of it,
I never thought about them differently. In fact, I used to do the same before. I cannot give full play to their understanding of none of them.
Their respective advantages. Okay. Now let's take a look at their respective purposes.
I. superkeys
This is not to mention, the simplest.
Ii. server controls
Hyperlink
Use the navigateurl attribute to specify the URL to jump.
It is mainly used by the user to determine when to convert pages, but the program is used to control the conversion target.
Iii. Program Control
1. response. Redirect ()
Server -------- notify client ---------- request jump to server
It is mainly used to pass the query string as part of the URL to another page, or the page to jump to is an HTML page
2. server. Transfer ()
The biggest feature of this method is that the URL is still the URL of the page before the jump.
It is mainly used to transfer the execution process to another ASPX page of the same web server. Because it is retained after the jump
Request and session values, and the data on the page before the jump can be used.
3. server. Execute ()
After this method is executed, the program control will return the next generation code of the jump code, which is equivalent to our modal window.
The Return Value of the redirected page.
It is often used to assist in selection operations, and then return the selected value to the current page.
With the above introduction, we should choose different jump methods when appropriate.

Comparison of four page Jump technologies in Asp.net web pages

There are four page navigation methods in Asp.net. How do I select one for your page?

· If you want users to decide when to convert a page and which page to go to, hyperlink is the most suitable.

· If you want to use a program to control the conversion target, but the conversion time is determined by the user, use the hyperlink control of the Web server to dynamically set its navigateurl attribute.

· If you want to connect a user to resources on another server, use response. Redirect.

· Use response. Redirect to connect users to non-aspx resources, such as HTML pages.

· If you want to retain the query string as part of the URL, use response. Redirect.

· If you want to transfer the execution process to another ASPX page of the same web server, you should use server. transfer instead of response. redirect, because server. transfer can avoid unnecessary network communication to achieve better performance and browsing performance.

· If you want to capture the output result of An ASPX page and insert the result to a specific location of another ASPX page, use server. Execute.

· To ensure that the HTML output is valid, use response. Redirect instead of server. Transfer or server. Execute.

About server. Execute,

This page navigation method is similar to calling the callback function for the ASPX page. The called page can access the form data and query string set of the calling page, therefore, set the enableviewstatemac attribute of the called page command to false.

By default, the output of the called page is appended to the current response stream. However, server. the execute method has an overloaded method that allows a textwriter object (or its sub-object, such as the stringwriter object) to obtain the output of the called page, rather than directly appending it to the output stream, on the original page, you can easily adjust the location of the output result of the called page.
