ASP. ASP 301 Redirect Implementation code _php tutorial

A lot of online tutorials on how to do 301 redirects, whether it's a full-site redirect or a single-page redirect.

1.1 No WWW domain name transferred to WWW domain name
Copy the code code as follows:

Rewriteengine on
Rewritecond%{http_host} ^bkjia.c0m [NC]
Rewriterule ^ (. *) $ http://www.bkjia.c0m/$1 [R=301,NC]

1.2 Entire station 301 redirects
Copy the code code as follows:

Options +followsymlinks
Rewriteengine on
Rewritecond%{http_host} ^bkjia.c0m [NC]
Rewriterule ^ (. *) $ http://www.bkjia.c0m/$1 [l,r=301]
Rewritecond%{http_host} ^www.bkjia.c0m [NC]
Rewriterule ^ (. *) $ http://bkjia.c0m/$1 [l,r=301]

Another way to do this is in the index.php tutorial in the root directory.
Copy the code code as follows:

Header ("http/1.1 301 Moved Permanently");
Header ("location:http://bkjia.c0m/");
Exit ();

Response.End
%>

3. ASP. NET Tutorial Host 301 redirect
ASP. NET:

response.status = "301 Moved Permanently";
Response.AddHeader ("Location", "http://www.bKjia.c0m");

Copy the code code as follows:

using System;
Using System.Collections.Generic;
Using System.Text;
Using System.Web.UI;
Using System.Web.UI.HtmlControls;
Namespace Classlib
{
public class Urlclass
{
private bool flag301 = false;//whether to start 301
private bool Isindex = false;//returns to the home page or remains on the current
///
constructor function
///
/// Whether to start 301
/// Page
/// Format www.xxx.com
Public Urlclass (bool FL, page page, string strurl)
{
flag301 = FL;
url301 (page, strurl);
}
///
Back to Home
///
///
/// Format www.xxx.com
public void url301 (Page page, string strurl)
{
301 Redirects
if (page.request.url.dnssafehost! = strURL && flag301 = = True)
{
Page.response.clear ();
Page.response.statuscode = 301;
Page.response.status = "301 movedpermanently";
Page.response.addheader ("location", "http://" + strURL);
Page.response.end ();
}
}
}
}

4 PHP 301 Redirects
Copy the code code as follows:

Header (' http/1.1 301 Moved Permanently ');//301 head issued
Header (' location:http://www. ') $strdomain. $request _uri);//jump to my new domain address

I wrote 301 code with the 301.inc.php file, and it was all referenced on the other file headers.
Copy the code code as follows:

//-----------------------------------
301 Redirects
$strdomain = "chinawecan.com";
$the _host = $_server[' http_host '); Get access to the domain name you entered
$request _uri = isset ($_server[' Request_uri ')? $_server[' Request_uri ': ";//determine the address after the part
if ($the _host!== ' www. $strdomain)//This is my previous domain name
{
/* "!==" is not exactly equal to the meaning, can also use "! =" does not equal, so that can be the previous domain name,
including Gcxirang.com, www.gcxirang.com, and the new domain I gcidc.net all redirected to www.gcidc.net*/
Header (' http/1.1 301 Moved Permanently ');//301 head issued
Header (' location:http://www. ') $strdomain. $request _uri);//jump to my new domain address
}
//----------------------------------
?>

The references are as follows:
Copy the code code as follows:

//-----------------------------------
301 Redirects
Include (' include/301.inc.php ');
?>
