The difference between a redirect and a page redirect, what does a web page non redirect mean

1. Add a bookmark at the beginning of the page, select the "Bookmark" command under the "Insert" menu, 2. Enter the name of the bookmark in the pop-up dialog box, such as "top", 3. Click "OK", and a bookmark logo will appear at the beginning of the page. 4. Enter "Return to top" at the end of the page and select it, 5. Press the Ctrl+K key to pop up the "Create Hyperlink" dialog box. In the "Bookmark" drop-down list, select the bookmark "top" just created, 6. Click "OK", and add a hyperlink to "Back to top".

7. Next, preview this web page, click "Back to top", and you can jump to the top of the page.

Forward is a jump on the server side, that is, a request from the client is sent to the server, and the server directly passes the information of the request-related parameters to other JSP or servlet of the server for processing, while SendReDirect is a jump on the client side, and the server will return a response header and a new URL address to the client. The browser will access the servlet or JSP that the new URL points to, which may not be the webservce on the original server.

Here are a few ways to redirect.

Redirects are also known as:PermanentRedirects, a** if doneRedirect, which means that all the metrics of this ** are completely transferred to the redirected page.

Search. Although the two domain names look the same, they are not, the former is a second-level domain and the latter is a first-level domain. And the search engine will include the two domain names separately, which will cause the weight of ** to be scattered, which is not the result we want, so we have to use itRedirect.

And. We'll find that we'll all jump to:

OpenchromeThe built-in debugging tools, as we see, are in the input, the page is reoriented to the rubber, hereis a temporary redirection.

If there is still traffic to these pages, a redirect should be done.

To think inapacheunder the implementationRedirects, which should be turned on firstapacheof the rewrite module, inapahceconfiguration filefound the following statement:

Put the previous note#Cancel it out.

And then in order toapacheYes.htaccessfile, inapacheconfiguration file, find.

Put one of themallowoverride noneInsteadallowoverride all, and then restartapache, which is created at the root of **.htaccessFile.

In.htaccessAdd the following statement to the file:

r stands for Permanent Redirect, which can also be usedorInstead, l represents the termination of the rewrite rule. nc is to ignore case.

Regular gear is used here, and you can refer to the manual for wheel gear regularization.

content, so this way is more recommended. tagcontentThe property is the time of the delay jump, and you must pay attention to setting the delay time to at leastsource, so if you want to avoid weight transfer, you should use this method.

PHP web page redirects should be like cracking using the header function.

Forward is a jump on the server side, that is, a request from the client is sent to the server, and the server directly passes the information of the request-related parameters to other JSP or servlet of the server for processing, while SendReDirect is a jump on the client side, and the server will return a response header and a new URL address to the client. The browser will access the servlet or JSP that the new URL points to, which may not be the webservce on the original server.

Differences:1Depending on the number of requests, the redirect requests the server twice in total; ** is the process of multiple processing of a request by returning to the user's browser through n JSP pages at a time;

2.The change of the link during the redirect, the redirect requests the server twice in the redirect and is twice different link addresses, and you can see that there is a change in the address bar of the browser; **In the process of redirecting, the browser requested the server once, and the server passed through n jsp pages and did not change the requested link address, because the user only requested once, so the link address did not change during the whole redirect, and it can be seen in the address bar of the browser.

3.The purpose is different, the redirect is simply to let the user access a new link, and ** is the server to get the user's request content and need to process part of it, so the purpose of the two is different.

There is an important difference between redirects and redirects: when used, the JSP container will use an internal method to call the target page, and the new page will continue to process the same request, and the browser will not be aware of the process. In contrast, the meaning of the redirect method is that the first page informs the browser to send a new page request.

Because, when you use redirects, the URL displayed in the browser becomes the URL of the new page, and when you use **, the URL remains the same. Redirects are slower than ** because the browser has to make a new request. At the same time, since the redirection method generates a new request, the objects in the request will not be available after a redirect.

How do you choose whether to redirect or **? Usually it's faster and keeps the object in the request, so it's the first choice. However, since the URL in the browser still points to the start page after **, if the current page is reloaded, the start page will be recalled.

If you don't want to see that, select **.

Difference between ** and redirects.

Redirect: All variables stored in the previous request are invalidated and enter a new request scope.

**: Variables stored in previous requests will not be invalidated, just like piecing two pages together.

There are so many typos that the meaning has changed!

Page Jump**

1.Can be with parameters.

2.Internal jumping, no secondary operation required.

Redirect 1Parameters are not allowed.

2.Return to redirect with the client (secondary operation).

Let's understand it this way.

When the customer applies for the service, he can access the page to be redirected to with the parameters. The URL address remains the same, and the client applies for the service, and the server returns to the client and tells you the redirection information, and you have to visit it again. URL address changes.

Summary. Redirects refer to automatically navigating users from one URL address to another. This is often used in web development and is often used to deal with situations such as page redirects, error page redirects, link updates, etc.

Therefore,"Web pages are not redirected"Indicates that the page will not change the URL or jump to a different page, but will remain on the current URL.

Hello dear! "Web pages are not redirected"This means that when you visit a web page, the URL of the web page does not change or jump to another page.

Kiss, in layman's terms"Web pages are not redirected"It can be understood that when you visit a web page, it will redirect you to a different page or change the current web page address. To put it simply, after opening this web page, the ** displayed on the address bar of the web page will not change, and it will not jump to other pages. You're still stuck browsing the same page as the lead short.

1.Adjustments (e.g. changes to the directory structure of web pages);

2.The page was moved to a new address;

3.Web extension change (e.g. the app needs to be changed.) php to. html or. shtml)。

In this case, if no redirection is done, the old address in the user's favorites or search engine database can only allow the visiting customer to get a 404-page hall no face error message, and the access traffic will be lost in vain; In addition, some ** that have registered multiple domain names also need to be redirected to let users who visit these domain names automatically jump to the main site, etc. Divination.
