301 Redirect

301 redirect is the most efficient and Search Engine Friendly method for webpage redirection. It’s not that hard to implement and it should preserve your search engine rankings for that particular page. If you have to change file names or move pages around, it’s the safest option. The code “301″ is interpreted as “moved permanently”.

You can Test your redirection with Search Engine Friendly Redirect Checker

Below are a Couple of methods to implement URL Redirection

IIS Redirect

  • In internet services manager, right click on the file or folder you wish to redirect
  • Select the radio titled “a redirection to a URL”.
  • Enter the redirection page
  • Check “The exact url entered above” and the “A permanent redirection for this resource”
  • Click on ‘Apply’

ColdFusion Redirect

<.cfheader statuscode=”301″ statustext=”Moved permanently”>
<.cfheader name=”Location” value=”http://www.new-url.com”>

PHP Redirect

<?
Header( “HTTP/1.1 301 Moved Permanently” );
Header( “Location: http://www.new-url.com” );
?>

ASP Redirect

<%@ Language=VBScript %>
<%
Response.Status=”301 Moved Permanently”
Response.AddHeader “Location”,”http://www.new-url.com/”
%>

ASP .NET Redirect

<script runat=”server”>
private void Page_Load(object sender, System.EventArgs e)
{
Response.Status = “301 Moved Permanently”;
Response.AddHeader(“Location”,”http://www.new-url.com”);
}
</script>

JSP (Java) Redirect

<%
response.setStatus(301);
response.setHeader( “Location”, “http://www.new-url.com/” );
response.setHeader( “Connection”, “close” );
%>

CGI PERL Redirect

$q = new CGI;
print $q->redirect(“http://www.new-url.com/”);

Ruby on Rails Redirect

def old_action
headers["Status"] = “301 Moved Permanently”
redirect_to “http://www.new-url.com/”
end

Redirect Old domain to New domain (htaccess redirect)

Create a .htaccess file with the below code, it will ensure that all your directories and pages of your old domain will get correctly redirected to your new domain.
The .htaccess file needs to be placed in the root directory of your old website (i.e the same directory where your index file is placed)

Options +FollowSymLinks
RewriteEngine on
RewriteRule (.*) http://www.newdomain.com/$1 [R=301,L]

Please REPLACE www.newdomain.com in the above code with your actual domain name.

In addition to the redirect I would suggest that you contact every backlinking site to modify their backlink to point to your new website.

Note* This .htaccess method of redirection works ONLY on Linux servers having the Apache Mod-Rewrite moduled enabled.

Redirect to www (htaccess redirect)

Create a .htaccess file with the below code, it will ensure that all requests coming in to domain.com will get redirected to www.domain.com
The .htaccess file needs to be placed in the root directory of your old website (i.e the same directory where your index file is placed)

Options +FollowSymlinks
RewriteEngine on
rewritecond %{http_host} ^domain.com [nc]
rewriterule ^(.*)$ http://www.domain.com/$1 [r=301,nc]

Please REPLACE domain.com and www.newdomain.com with your actual domain name.

Note* This .htaccess method of redirection works ONLY on Linux servers having the Apache Mod-Rewrite moduled enabled.

How to Redirect HTML

Please refer to section titled ‘How to Redirect with htaccess’, if your site is hosted on a Linux Server and ‘IIS Redirect’, if your site is hosted on a Windows Server.

PHP error 5.2.4 Getting error “Error in my_thread_global_end(): 1 threads didn’t exit”

Thursday, October 25th, 2007

We have noticed a few web server admins to be getting an error message Getting error “Error in my_thread_global_end(): 1 threads didn’t exit” when running php on IIS windows servers in CGI. the issue is caused by libmysql.dll found in php directory. The file size for the libmysql.dll was 1.94 MB (2,035,712 bytes).

To fix the issue and clear the error message, you must replace libmysql.dll with an earlier version from release 5.2.1 of PHP.

I noticed many people were not able to get their hands on it so we have uploaded it to our server to make it easily availble.
Download php mysql libmysql.dll

DOS IF command to check file if exist

Friday, August 10th, 2007

Simple opertations can seem easy but in some instances it is challenging.

Many network administrators can find this useful when deploying new files to the company computer using batch files.

Here is some good info on how to use the if statement.

Performs conditional processing in batch programs.

IF [NOT] ERRORLEVEL number command
IF [NOT] string1==string2 command
IF [NOT] EXIST filename command

  NOT               Specifies that Windows XP should carry out
                    the command only if the condition is false.

  ERRORLEVEL number Specifies a true condition if the last program run
                    returned an exit code equal to or greater than the number
                    specified.

  string1==string2  Specifies a true condition if the specified text strings
                    match.

  EXIST filename    Specifies a true condition if the specified filename
                    exists.

  command           Specifies the command to carry out if the condition is
                    met.  Command can be followed by ELSE command which
                    will execute the command after the ELSE keyword if the
                    specified condition is FALSE

The ELSE clause must occur on the same line as the command after the IF.  For
example:

    IF EXIST filename. (
        del filename.
    ) ELSE (
        echo filename. missing.
    )

The following would NOT work because the del command needs to be terminated
by a newline:

    IF EXIST filename. del filename. ELSE echo filename. missing

Nor would the following work, since the ELSE command must be on the same line
as the end of the IF command:

    IF EXIST filename. del filename.
    ELSE echo filename. missing

The following would work if you want it all on one line:

    IF EXIST filename. (del filename.) ELSE echo filename. missing

If Command Extensions are enabled IF changes as follows:

    IF [/I] string1 compare-op string2 command
    IF CMDEXTVERSION number command
    IF DEFINED variable command

where compare-op may be one of:

    EQU – equal
    NEQ – not equal
    LSS – less than
    LEQ – less than or equal
    GTR – greater than
    GEQ – greater than or equal

and the /I switch, if specified, says to do case insensitive string
compares.  The /I switch can also be used on the string1==string2 form
of IF.  These comparisons are generic, in that if both string1 and
string2 are both comprised of all numeric digits, then the strings are
converted to numbers and a numeric comparison is performed.

The CMDEXTVERSION conditional works just like ERRORLEVEL, except it is
comparing against an internal version number associated with the Command
Extensions.  The first version is 1.  It will be incremented by one when
significant enhancements are added to the Command Extensions.
CMDEXTVERSION conditional is never true when Command Extensions are
disabled.

The DEFINED conditional works just like EXISTS except it takes an
environment variable name and returns true if the environment variable
is defined.

%ERRORLEVEL% will expand into a string representation of
the current value of ERRORLEVEL, provided that there is not already
an environment variable with the name ERRORLEVEL, in which case you
will get its value instead.  After running a program, the following
illustrates ERRORLEVEL use:

    goto answer%ERRORLEVEL%
    :answer0
    echo Program had return code 0
    :answer1
    echo Program had return code 1

You can also using the numerical comparisons above:

    IF %ERRORLEVEL% LEQ 1 goto okay

%CMDCMDLINE% will expand into the original command line passed to
CMD.EXE prior to any processing by CMD.EXE, provided that there is not
already an environment variable with the name CMDCMDLINE, in which case
you will get its value instead.

%CMDEXTVERSION% will expand into a string representation of the
current value of CMDEXTVERSION, provided that there is not already
an environment variable with the name CMDEXTVERSION, in which case you
will get its value instead.
