Www and non www sites

I have a domain say http://www.testexample.com. When I login to http://www.testexample.com and come back to http://testexample.com in browser; the logged in user information is not displayed.

I know that the both of the above are treated differently and hence i开发者_StackOverflow社区t is not retaining the session for http://www.testexample.com while accessing http://testexample.com.

Please let me know if cakephp has a way to do a match on the TLD. So whenever I type http://testexample.com it should take session for http://www.testexample.com

I am using the following code to redirect from one URL to the other

RewriteCond %{HTTPS} off   
RewriteCond %{HTTP_HOST} ps6309 [NC]   
RewriteRule ps6309.domain.co.in [L,R=301]

this is on my local test machine. This works sometimes and sometimes doesn't.

Also I have added the rewritelog directive to my httpd.conf file. But the log file is not getting updated. Please let me know if anyone has any pointers to this.

Use .htaccess to redirect all http://domain.com -> http://www.domain.com

RewriteCond %{HTTP_HOST} !^www\.domain\.com
RewriteRule ^(.*)$ http://www.domain.com/$1 [R=permanent,L]

Set the domain for the cookie as testexample.com, then it can be shared across sub domains as well as not worrying about www.

If you have many projects and don't want to hard code your domain name on .htaccess again and over again, try this code:

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www\.
RewriteRule (.*) http://www.%{HTTP_HOST}/$1 [R=301,L]

this will redirect non-www to www. While you're using cakephp, then put it on your .htaccess which is located at /webroot

Try ini_set('session.cookie_domain', $domain); (documented as ini_set session.cookie_domain and session_set_cookie_params()), where $domain is your domain name prefixed by a .. So, using the domain example.com (per rfc 2606), you'd use:

ini_set('session.cookie_domain', '.example.com');

Please note that this is not a CakePHP specific solution - looking at the code for CakeSession, session.cookie_domain is never set, meaning that it falls to it's default value. Stuffing that line in your app/config/bootstrap.php or app/config/core.php should do it for you.
