Hey all,

I've got css3pie working fine for my site, but I have come across this issue.

If I have say http://www.domain.com it works fine. But if I have london.domain.com then pie fails to work.

Has anyone else come across this issue?

Just so you know, I am using mod_rewrite.

Edit: I have also built the latest build on git and its the same problem. So if anyone can suggest "anything" to fix this, would be great.

Thanks

IE enforces a same-domain restriction on .htc behaviors. So the .htc file must be served from the exact same domain (including subdomain) as the HTML file that references it. Is that perhaps what you're running into?

Hi Jason,

Yes, I thought that would be the issue, so I tried a few things last nite.

1) Turn off mod_rewrite, just in case apache was doing something with the url.
2) prefix http://www.domain.com/ into the <link> to load my css

I found that www. works fine. However when I change to a subdomain and change the css link to load from the subdomain, it still doesn't work.

So the same-domain restriction shouldn't really be an issue here. As I'm pulling the css from the same domain as the .html file is being called from.

Is there a way to find where PIE is being loaded from?

Is there any help you can give me to resolve this?

Thanks

I'd recommend using a tool like Fiddler to see exactly what HTTP requests are being made. This should tell you if PIE.htc is being loaded from the correct domain, and if it's being served with the correct content-type header.

That's strange indeed. Unfortunately the behavior loading mechanism is internal to IE so there's nothing we can do to change it.

I would like to know better why IE is choosing the www. subdomain. Can you think of anything in your setup that would force that? A <base> tag, some meta tag or http header that might make IE load dependencies from a different subdomain?

Great, thanks for letting me know it was the <base> tag that was doing it. I'll be sure to add that to the upcoming troubleshooting guide as a possible gotcha.
