In order to upload files to S3 using Flash runtime, one should start by placing crossdomain.xml into the bucket.
|
||
|
|
crossdomain.xml can be as simple as this:
|
||
|
|
|
||
|
|
<?xml version="1.0"?>
|
||
|
|
<!DOCTYPE cross-domain-policy SYSTEM "http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd">
|
||
|
|
<cross-domain-policy>
|
||
|
|
<allow-access-from domain="*" secure="false" />
|
||
|
|
</cross-domain-policy>
|
||
|
|
|
||
|
|
In our tests SilverLight didn't require anything special and worked with this configuration just fine. It may fail back
|
||
|
|
to the same crossdomain.xml as last resort.
|
||
|
|
|
||
|
|
!!!Important!!! Plupload UI Widget here, is used only for demo purposes and is not required for uploading to S3.
