Issue + solution: I have a domain which needs to forward to another url with case sensitive URL. I used the domain forward form in the co-domain tab. The forward URL should be something like http://www.mydestdomain.com/pageXYZ.html while ISPconfig forces to lowercase and will forward to http://www.mydestdomain.com/pagexyz.html The piece of code responsible to force lowercase is in the file /root/ispconfig/scripts/lib/config.lib.php: PHP: if(substr($domain["domain_weiterleitung"],0,4) == "http" || substr($domain["domain_weiterleitung"],0,4) == "HTTP"){ $domain["domain_weiterleitung"] = [COLOR="Red"]strtolower[/COLOR]($domain["domain_weiterleitung"]); if(substr($domain["domain_weiterleitung"],-1) == "/") $domain["domain_weiterleitung"] = substr($domain["domain_weiterleitung"],0,-1); $rewrite_rule .= "\nRewriteRule ^/(.*) ".$domain["domain_weiterleitung"]."/$1 [L,R]"; } else { //if(substr($domain["domain_weiterleitung"],-1) != "/") $domain["domain_weiterleitung"] .= "/"; if(substr($domain["domain_weiterleitung"],0,1) != "/") $domain["domain_weiterleitung"] = "/".$domain["domain_weiterleitung"]; $rewrite_rule .= "\nRewriteRule ^/(.*)$ http://".$servername.$domain["domain_weiterleitung"]."$1 [R]"; } So locate the strtolower( ) call and remove it. This will prevent the forward URL to be converted to lowercase. the correct result (after fix) in /etc/httpd/conf/vhosts/Vhosts_ispconfig.conf: ewriteEngine on RewriteCond %{HTTP_HOST} ^mysourcedomainn\.com [NC] RewriteRule ^/(.*) http://www.mydestdomain.com/pageXYZ.html?/$1 [L,R] RewriteCond %{HTTP_HOST} ^www\.mysourcedomain\.com [NC] RewriteRule ^/(.*) http://www.mydestdomain.com/pageXYZ.html?/$1 [L,R] Furthermore you cannot forward the main domain, but only the co-domain. I had to change the www of the main domain into 'forward' (or something else never used), then make two co-domains, one with www and one without and both to forward to the new URL. Somthing ISPConfig could implement?
