Neuer Domain Name den Suchmaschinen melden

Dies sollte immer mit einer 301 Status Meldung erfolgen. <HIGHLIGHTSYNTAX><?php header("Status: 301 Moved Permanently"); header("Location: http://www.YOUR-NEW-DOMAINNAME.com"); exit; ?></HIGHLIGHTSYNTAX>

Weiterleitungen bei bestimmten Domainnamen

Dies kann erreicht werden, in dem in die index.php Datei (im Kopfteil) ein Redirect Script eingebunden wird. Beispiel wie folgt:

Datei: index.php <HIGHLIGHTSYNTAX> require_once dirname(__FILE__).'/customizing/redirect.php'; </HIGHLIGHTSYNTAX>

Datei: customizing/redirect.php <HIGHLIGHTSYNTAX> <?php /**

• Weiterleitungsscript
• COMVATION AG Switzerland
• www.contrexx.com
• redirect.php // als Includedatei
• /

$redirectDomain = "yourdomain.com"; $redirectDomain2 = "yourdomain2.com";

if (empty($_SERVER['argv'])) { if (substr($_SERVER['HTTP_HOST'], 0, 4) == 'www.') { $host = strtolower(substr($_SERVER['HTTP_HOST'], 4)); } else { $host = strtolower($_SERVER['HTTP_HOST']); } if($host == "$redirectDomain" || $host == "$redirectDomain2") { $newLocation = "index.php?page=100"; // Example header('Location: '.$newLocation); exit; } } ?> </HIGHLIGHTSYNTAX>

Globale Seitentitel bei bestimmten Domainnamen

Sie möchten den globalen Seitentitel (z.B. <title>[[GLOBAL_TITLE]]</title> ) bei bestimmten Domain Aliasen anpassen. Dies kann erreicht werden, in dem die index.php Datei wie folgt angepasst wird:

Datei: index.php <HIGHLIGHTSYNTAX> //------------------------------------------------------- // set global template variables //-------------------------------------------------------

if (substr($_SERVER['HTTP_HOST'], 0, 4) == 'www.') { $host = strtolower(substr($_SERVER['HTTP_HOST'], 4)); } else { $host = strtolower($_SERVER['HTTP_HOST']); }

switch ($host){ case "YOURDOMAIN.COM": $globalTitle = "Contrexx ist ein cooles CMS"; break; case "YOURDOMAINXYZ.COM": $globalTitle = "Contrexx ist verdammt cool!"; break; default: $globalTitle = $_CONFIG['coreGlobalPageTitle']; break; } </HIGHLIGHTSYNTAX>

Damit es einwandfrei funktioniert, müssen Sie noch $_CONFIG['coreGlobalPageTitle'] mit $globalTitle ersetzten, das finden sie unter: "set global template variables".

URL Optimierungen

Quelle: HTML5 Boilerplate

Suppress or force the "www." at the beginning of URLs

# The same content should never be available under two different URLs - especially not with and
# without "www." at the beginning, since this can cause SEO problems (duplicate content).
# That's why you should choose one of the alternatives and redirect the other one.

# By default option 1 (no "www.") is activated. Remember: Shorter URLs are sexier.
# no-www.org/faq.php?q=class_b

# If you rather want to use option 2, just comment out all option 1 lines
# and uncomment option 2.
# IMPORTANT: NEVER USE BOTH RULES AT THE SAME TIME!

# ----------------------------------------------------------------------

# Option 1:
# Rewrite "www.domain.com -> domain.com" 

<IfModule mod_rewrite.c>
  RewriteCond %{HTTPS} !=on
  RewriteCond %{HTTP_HOST} ^www\.(.+)$ [NC]
  RewriteRule ^(.*)$ http://%1/$1 [R=301,L]
</IfModule>

# ----------------------------------------------------------------------

# Option 2:
# To rewrite "domain.com -> www.domain.com" uncomment the following lines.
# Be aware that the following rule might not be a good idea if you
# use "real" subdomains for certain parts of your website.

# <IfModule mod_rewrite.c>
#   RewriteCond %{HTTPS} !=on
#   RewriteCond %{HTTP_HOST} !^www\..+$ [NC]
#   RewriteCond %{HTTP_HOST} (.+)$ [NC]
#   RewriteRule ^(.*)$ http://www.%1/$1 [R=301,L]
# </IfModule>

Add/remove trailing slash to (non-file) URLs

# Google treats URLs with and without trailing slashes separately.
# Forcing a trailing slash is usually preferred, but all that's really
# important is that one correctly redirects to the other.

# By default option 1 (force trailing slash) is activated.

# ----------------------------------------------------------------------

# Option 1:
# Rewrite "domain.com/foo -> domain.com/foo/"

# <IfModule mod_rewrite.c>
#   RewriteCond %{REQUEST_FILENAME} !-f
#   RewriteCond %{REQUEST_URI} !(\.[a-zA-Z0-9]{1,5}|/|#(.*))$
#   RewriteRule ^(.*)$ /$1/ [R=301,L]
# </IfModule>

# ----------------------------------------------------------------------

# Option 2:
# Rewrite "domain.com/foo/ -> domain.com/foo"

#<IfModule mod_rewrite.c>
#  RewriteRule ^(.*)/$ /$1 [R=301,L]
#</IfModule>
