What the programing language can send http post or get from client in web brower ?
i think flash actionscript or ajax or java applet not working for cross domain security thanks
Nothing in the browser sandbox will get past cross-domain security (which is exactly the point of having a sandbox in the first place).
You'd have to write a native browser plugin or use a Java applet that asks for "unlimited system access".
Another option would be to use the one domain that you can access via XHR to act as a proxy (have some code there that fetches the result from the domain you really want to access). You can even forward cookies and such, but for the target domain it looks like the request is coming from your data center (not the end user's browser).
