Cross Domain Ajax: <script> tag manipulation

Should you need to access servers in a different domain we've enabled a new remoting scheme. From DWR 2.0 you can use manipulation of <script> tags in addition to XMLHttpRequest or iframes. To use is you just need to do the following:
DWREngine.setMethod(DWREngine.ScriptTag);

To allow cross-domain script tag requests you need to add the following incantation to web.xml:

<init-param>
<param-name>allowGetForSafariButMakeForgeryEasier</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>crossDomainSessionSecurity</param-name>
<param-value>false</param-value>
</init-param>
<init-param>
<param-name>allowScriptTagRemoting</param-name>
<param-value>true</param-value>
</init-param>

To configure the client where to send cross-domain requests, set the ._path variable for the remote interface in question:

Remote._path = 'http://otherdomain.com/webapp/dwr';
Remote.someFunction();

Cross-domain remoting may not work properly with reverse ajax.

<script type='text/javascript' src='http://a.com/dwr/interface/regutil.js'></script>
<script type='text/javascript' src='http://a.com/dwr/engine.js'></script>

<script type='text/javascript' src='http://a.com/dwr/util.js'></script>

dwr.engine.setMethod(dwr.engine.ScriptTag);
regutil._path = 'http://sso.dxy.cn/dwr/';
