Serving static content from cookieless domain - need help

Hello

I have a problem with optimizing my vBulletin 4.0.3 Forum.

my forum runs on Patientenfragen.net - wir haben die Antworten

I have created 6 subdomains for static content (Images only currently)

http://static1.patientenfragen.net/
http://static2.patientenfragen.net/

I have set the cookie domain for my forum in the acp cookie settings to use patientenfragen.net as cookie domain instead of .patientenfragen.net

In my understanding this should exclude the subdomains from using the vbulletin cookie.

On the subdomains there is no single html nor php file.

Only the images and a htaccess with the following content:

AddDefaultCharset Off
FileETag None

ExpiresActive On
<IfModule mod_expires.c>
ExpiresByType image/gif A2592000
ExpiresByType image/png A2592000
ExpiresByType image/jpg A2592000
ExpiresByType image/jpeg A2592000
ExpiresByType image/x-icon A2592000
ExpiresByType text/plain A2592000
ExpiresByType text/css A2592000
ExpiresByType application/x-javascript A2592000
ExpiresByType application/pdf A2592000
ExpiresByType application/x-shockwave-flash A2592000
</IfModule>

After clearing my browser cache, apc cache and delete all cookies from my website in my browser PageSpeed still tells me that the static... subdomains serve cookies.

The cookies still served for .patientenfragen.net are:
- lastvisit
- np_notices_displayed
- lastactivity
- sessionhash
- cpsession
- userid
- password

as well as the google analytics cookies
- _utma
- _utmb
- _utmc
- _utmz

I use the analytics code suggested by digitalpoint and changed .domain.com to domain.com:

<script type="text/javascript">
google_analytics_uacct = "UA-XXXXX-X";google_analytics_domain_name = "patientenfragen.net";var _gaq = _gaq || [];_gaq.push(['_setAccount', 'UA-XXXXX-X'],['_setDomainName', 'patientenfragen.net'],['_trackPageview']);(function() {var ga = document.createElement('script');ga.type = 'text/javascript';ga.async = true;ga.src = 'http://www.google-analytics.com/ga.js';(document.getElementsByTagName('head')[0] || document.getElementsByTagName('body')[0]).appendChild(ga);})();
</script>

How can I fix this?

Solved the problem by defining www.patientenfragen.net as cookie domain.

Just in case some people have the same issue

If anyone thinks that the above move is not a good Idea I am all ears, currently I can't see a downside to it

In this case I recommend you a custom redirection for non-www to www to prevent another cookie problem in your forum. That will fix another issue that you can have.

I set the google analytics domain to .www.patientenfragen.net also and no other scripts set cookies on my domain.
The images load now without cookies.

The redirect to www. is in place for years now but thanks for the advice.

Maybe if in the future conflicts arise I will use on of my other domains for the static content but for now it works.
