I am trying to access flv from flash media server which is in my pc…F:/FlashServer/.

nc.connect (“rtmp://localhost/vod/”);

its throwing an error “SecurityError: Error #2123: Security sandbox violation: [http://127.0.0.1/flexcfm\_login/KMG\_TV/KMG\_TV.swf](http://127.0.0.1/flexcfm_login/KMG_TV/KMG_TV.swf) cannot access rtmp://localhost/vod/. No policy files granted access.”

[http://127.0.0.1](http://127.0.0.1) : it is coldfusion server ip.

I put an crossdomain.xml file in F:/FlashServer/

\<?xml version=“1.0”?\>  
\<!DOCTYPE cross-domain-policy  
SYSTEM

“[http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd](http://www.macromedia.com/xml/dtds/cross-domain-policy.dtd)”\>  
\<cross-domain-policy\>  
\<allow-access-from domain=“127.0.0.1” /\>\<allow-access-from

domain=“[http://127.0.0.1/flexcfm\_login/KMG\_TV/bin-debug/](http://127.0.0.1/flexcfm_login/KMG_TV/bin-debug/)” /\>\<allow-access-from domain="\*"

/\>  
\</cross-domain-policy\>

Still this error is coming …

Any help is appreciated.

The crossdomain file has to be in the root of wherever your localhost is set up on the comp.
