I have am setting up a social network script, it has both a desktop and a mobile version of the site. When a mobile device tries to browse the site, the mobile page is served with the url www.example.com/mobile I want a .htaccess rewrite rule that can change all the www.example.com/mobile url to m.example.com without actually redirecting to the subdomain m This is what I could come up with 

RewriteCond %{HTTP_HOST} ^m.example.com RewriteRule (.*) http://www.example.com/mobile/$1 [R=301,L]

But i am getting an error... Rewitecond: Bad flag delimiters How do I fix this or what would be a better way to do this?

P.S I dont have a .htaccess file I am setting up these rules directly inside the httpd.conf directive. I don't think that is going to make any difference but just thought it would be better to mention... just in case.

I have since moved enabled .htaccess and taken the rewrite rules out of the httpd.conf file and tested if .htaccess works and also that mod_rewrite is enabled. I am using this code to verify that mod_rewrite is indeed enabled

<?php ob_start(); phpinfo(INFO_MODULES); $contents = ob_get_contents(); ob_end_clean(); var_dump(strpos($contents, 'mod_rewrite') !== false); ?>

When i run this file i get an output bool(true) Also I have noticed rewrite rules like the one below is working fine

# 301 redirect if missing www. RewriteCond %{HTTP_HOST} !^$ RewriteCond %{HTTP_HOST} !^www\. [NC] RewriteCond %{HTTPS}s ^on(s)| RewriteRule ^ http%1://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

But rules these rules won't work

RewriteRule ^link([^/]*).html$ rewrite.php?link=$1 [L] RewriteCond %{HTTP_HOST} ^m.jukpac.com RewriteRule (.*) http://www.jukpac.com/mobile/$1 [R=301,L]

Why are my rewrite rules only partially working? :-/

Below is a a snap of the rewrite logs

  • You've got nothing in your logs attached showing where you try these rules which does not work. Commented Jan 25, 2014 at 8:25
  • I am discarding this question and this silly error, tired sick of it moving to nginx based server at the very least I can understand what is going wrong in it with nginx Commented Jan 25, 2014 at 9:14

It looks like you get a parse error because RewriteCond statements seeks to interpret [R=301,L], although that one is intended for the RewriteRule.

Try putting them on different lines like this:

 RewriteCond %{HTTP_HOST} ^m.example.com RewriteRule (.*) http://www.example.com/mobile/$1 [R=301,L]

  • your solution fixed the error but I didn't get the required results. www.example.com/mobile/ doesn't change to m.example.com plz help me write the rules that you think can achieve what I want Commented Jan 15, 2014 at 20:04
  • well, this example should redirect the m.example.com, so try enabling some logging httpd.apache.org/docs/current/mod/mod_rewrite.html and check your logs. It will say what the value of HTTP_HOST is while evaluating each request. Commented Jan 15, 2014 at 22:36
  • Mod rewrite is enabled I have tested it, tried to add the rewrite log getting a 500 .. Editing the question to show the codes I am using to verify that mod_rewrite is enabled please take a look Commented Jan 16, 2014 at 4:18
  • you need to enable rewrite logging to determine where you fail. Error 500 is not related to rewrite rules. Commented Jan 16, 2014 at 17:53
  • take the php stuff out of the equation for now -- just monitor the mod rewrite logs and you're gonna find out where you fail for sure. Commented Jan 24, 2014 at 19:59
