Cross-origin flash Problems

When an HTTP request is sent to resources of an external website in flash as, the cross-origin issue of Flash is caused.

When a cross-origin problem occurs, flash will first access the crossdomain. xml file in the root directory of the website of the other party.

The crossdomain. xml file defines which websites have the permission to access resources of the website.

Therefore, if we want to allow cross-origin access to resources on other websites, we need to add the crossdomain. xml file to the root directory.

 

The content of crossdomain. XML is as follows:

<? XML version = "1.0"?>
<Cross-domain-Policy>
<Allow-access-from domain = "*"/>
</Cross-Domain-Policy>

 

The configuration is simple. Domain indicates the domain name that can be accessed.
