Adobe Socket Policy File Server Problems

Question

Has anyone been able to successfully implement a service to serve the required socket policy file to FlashPlayer?

I am running the Python implementation of the servi

Answer 1

Do you send a trailing 0-byte after the

<cross-domain-policy>
     <allow-access-from domain="*" to-ports="*" />
</cross-domain-policy>

Check the http://www.lightsphere.com/dev/articles/flash_socket_policy.html

Answer 2

Assuming you are using AS3...

You can override crossdomain.xml policy files in your flash like this:

Security.allowDomain("*");
Security.allowInsecureDomain("*");

But if you need crossdomain.xml make sure it is in your root of the server you are trying to access. Also try a complely base simple version to make sure it works such as:

<?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="*" />
</cross-domain-policy> 

Make sure it is named crossdomain.xml and in your root.

You can also change the policy file to another server or filename like this:

Security.loadPolicyFile("http://www.example.com/sub/dir/pf.xml");

If you are using AS2/flash8 (first off I am sorry) then you will need to be sure crossdomain.xml is in the root of the server you are hitting.

I've hit this a couple of times now, trying to use someone else's policy server, and writing my own. The elements that I've found that all need to be there:

• listen on socket 843.
• When receiving a new connection, read all data. Don't just send the policy on connect!
• optionally, you can test if the received data is a correct policy request, or just ignore it. I haven't seen a good reason to validate in my usage.
• send the xml with the trailing "\0" byte.
• close the socket!
• more than likely you need the secure="false" option in the allow-access-from section of the policy.

Answer 4

If you're using Debian, I've written an Apache module for serving Adobe socket policy files that is available at:

http://socketpolicyserver.com

The package includes working configuration files in:

/usr/share/doc/libapache2-mod-socket-policy-server/examples/

Answer 5

Try hosting the policy file at port 843, assuming your admin will allow access to 843. Here's a link that tells you about socket policy files.

Answer 6

There's now a module for the Apache webserver to server socket policy files compatible with the new Flash 9.whatever and Flash 10+ which require socket policy files to be served using the Adobe socket protocol.
