Header Redirect With PHP

[abuzant3d]

I'v been reading information about browser redirections using PHP, i have noticed
some sites saying that using a header command like

header("Location: page.html"); 

is enough, while on other community sites people say no, it is better to use the following snippet of code, which does the same job ...

header("HTTP/1.1 301 Moved Permanently");
header("Location: page.html");
header("Connection: close"); 

will you please try discussing this here, effects on browser, server, server load, page process time, load time and other aspects ?? which is in yourpoint of view, is better !!!

Thanks in advance...

if you redirect with php the status is set to REDIRECT 302 inless you have already set status like in your code. (see php manual)
your code should produce a server responce like this:
<--snip-->
Server Response: http://www.mydomain.com
Status: HTTP/1.1 302 Found
Date: Wed, 18 Jun 2003 22:04:36 GMT
Server: Apache/1.3.27 (Unix) mod_log_bytes/1.2 mod_bwlimited/1.0 php/4.3.1 FrontPage/5.0.2.2510 mod_ssl/2.8.14 OpenSSL/0.9.6b
X-Powered-By: php/4.3.1
Status: HTTP/1.1 301 moved permanently
Location: http://www.mydomain.com/mydir
Keep-Alive: timeout=15, max=100
Connection: Close
Transfer-Encoding: chunked
Content-Type: text/html
<--snap-->
on the client site for your browser there should be no effects (except from the redirecting action) and i don't think page process time is much bigger if you use the second code.

Actually, you should specify an absolute URL when sending Location: headers to the browser, e.g.

header('Location: page.html'); // is technically incorrect 

header('Location: [url]http://www.mysite.com/page.html[/url]'); // the right way to do it 

Whether or not you include the other lines is up to you, however in my experience the server does this for you and so there is no need to add them manually.
