Have you tried using YSlow? It’s a good plugin to speed up your webpages also.

www it’s a subdomain (common for a site) . In your case set the cookie for http://www.domain.com and load pictures from images.domain.com.

Thanks,
So, if I don’t want to use cookies in the subdomains I only have to write the following into the www site:
setcookie(“testVar”, “someValue”, time() + 3600, ‘/’, ’subdomain.domain.com’)
Am I right? Or should I also do something in the subdomains?

Thanks and regards!

@Eric, yes, GA sets wide-site cookie.

@Marc, use domain value on setcookie function like:

setcookie("testVar", "someValue", time() + 3600, '/', 'www.domain.com')

setcookie("testVar", "someValue", time() + 3600, '/', 'subdomain.domain.com')

You can set cookie on domain www and leave nocookie on others(images, css...whatever you use for your media content).

Hope this helps

Hi, thanks for your post.
In the two last comments you say to use setcookie(), how can I do it?
Regards!

Well, that’s the odd part. I did used setcookie with fixed domain to http://www.url.com but didn’t seem to matter. Suppose it’s the GA settings this 430 bytes cookies..

I read somewhere that google analytics script is setting a wide-site cookie (subdomains included). If you do need GA you have to use a cookiless domain, and if not use setcookie() with fixed domain.

Yes, I did that on one of my sites because my cookie was around 1k * 100K images – you do the math.

I’m trying to reduce the bandwith of a website which has about 60k visitors a day with 25 traffic. My cookie is just 430bytes but this ads up with a lot of requests of every image used in my website. Thank you for your answer ;)

Cookie goes on every piece of data you get from server (image/html, everything).

From what I understand is that the cookie is send in every request to the server which costs bandwidth and speed. But is it send to every image or just on every browser refresh?
