I am facing a very annoying problem with HighWinds CDN.
I am using Origin pull for the images on the site, size of which ranges from 20KB to 1MB of type jpg, gif and png.

The thing is that, if the user is visiting the first page the images takes some time to load for the first time which is normal(approx 30 secs. as there are lots of images). But if the user navigates to some other page and than come back to the the first page the images load from the CDN again and it again takes 30-40 sec to fully load the page which was already visited earlier. I guess this time images should have loaded from the browser cache than from the server.

I raised a support ticket(through their reseller) but got a reply that "this is how Highwinds CDN works".

Is there any workaround to fix this. Any way by which we can explicity store the images in browser cache for the current session and thus bypass it to load everytime from CDN.

This is a known problem with Highwinds. It will cache files *IF* the end user enables 3rd party cookies. Considering it's a security hole, that's not a good solution. But otherwise, there's no reasonable workaround.

The solution: Find another CDN provider.

So they don't support cache expiration headers?

They do, sort of, but they do it through setting 3rd party client-side cookies. The cookies being sent back to the server by the client determines if what is cached by the client browser is used, or if the content is sent again.

For small files, Highwinds is practically unusable. But then again, it wasn't designed for that.... it was designed primarily for the distribution of larger, video files.

They were supposed to have a greatly improved system in place by now, but it sounds like that's not the case.

Yes, for any delivery network which is delivering images this should be a bare minimum feature.:(

highwinds best for rich media delivery and they never say they offering service for boost website speed :D

they use some url forwarding system that will make some delay and every time web page load see some images not loading properly may be due to that cache thing

we use highwinds to push streaming traffic that was very nice :)

Time to change.

You may look into other options that is catered for small obj delivery CDN.
