if i understood right, google and seo are not affected if e.g. i load images on articles on http://pocerosmadrid.biz using desatascosmadrid.biz/images/1.jpg or likewise…?

Yes you understood correctly, serving images from other domain will not be effected. I am assuming that desatascosmadrid.biz is also a good quality domain, if you use some domain which has been involved in spamming, or banned by google, it may effect.

loading time due to cookie loading is high, so could/should i use a cookieless subdomain

For normal sites impact on loading time due to cookies is not high. Using different domain will already give parallel download for images etc. The images domain don’t always have to be cookieless. In your case the domain desatascosmadrid.biz is altogether a different domain, so cookies will not be sent with images.

how do i set it up on wordpress if i’m only an end-user and have no access to server config?

I don’t know if and how the image url can be changed for the images in wordpress, but i am sure there must be a way. If possible we can change the url of images when adding images from media library.

I hope i answered your queries, thanks

hi,
i read through the whole article with lots of interest but lack of knowledge…
i run wordpress on two hosts, using c-names and a-records, with a total of 400 domain names
i run into the problem of file amount limitation, which is why i want to serve iamges from the main domain http://desatascosmadrid.biz
now, if i understood right, google and seo are not affected if e.g. i load images on articles on http://pocerosmadrid.biz using desatascosmadrid.biz/images/1.jpg or likewise…?!!
but, if understood, loading time due to cookie loading is high, so could/should i use a cookieless subdomain? and how do i set it up on wordpress if i’m only an end-user and have no access to server config?
sorry if my question is repetitive, i just couldn’t figure out what exactley would be applicable in my case
thanks in advance for any help

@marc
The message is there because session cookies is being set for *.mywebsite.com and not limited to http://www.mywebsite.com. If you don’t need sessions than keep session_start() commented. At the moment i don’t know how to limit session cookie to a domain (as this cookie is not set from set_cookie() function), I think there must be some configuration to tell domain of the session cookie. Please try to set cookie “PHPSESSID” via set_cookie function and give domain param as http://www.mywebsite.com before the session_start, I am not sure if it will work but no harm in trying.

Hello,

I am trying the same for my website. So i created a static.mywebsite.com subdomain. I still see the message about cookieless domain in the “page speed” addon for mozzila.
Weird since i dont set any cookies on my website? I do use a session.
Commenting the session_start() in the beginning of my php script removes the “cookieless domain” warning. Un-commenting session_start() in my php script results in giving me the freakin warning again.
Seems like a session is setting cookies too??? I dont get it.

Can anyone explain this to me? And what should i do to fix it?

Greetings,

Marc

If you are using linux machine you can overcome this issue by using soft links. In this way you images will be available from both (main and subdomain) so you new images will be moved to subdomain and old files will still accessible. Another method will be to rewrite old urls to new domain through .htaccess.

Hi !

nice article and well explained .

I ran into lots of articles to serve static content from a cookieless domain , but this one seems to be the easiest for me to follow.

I am using vbulletin software , although I do not know where to find this PHP function , but it should be there some where.

now I am facing two issues here :

the first one is that I have to move files physically to their proper subdomain folders right ?

the second one is , I am wondering if I moved all images , css , java etc to a cookie-less sub domain , how do I overcome the issue of ( having posts around with the old images urls like ( http://www.mydomian.com/images/whatever.jpg ).

cause I don’t allow my community to upload images on any other server.

Thank you again for sharing such useful article .

Yes any domain can be used, as image domain does not matter much.

No, the code is just a sample. you need to find similar code/function in your site and make it use a specific domain, so other sub domains can become cookie less domains
