Last week, I wanted to make some Ajax requests from a page generated by some web application to another web application. These two applications are hosted in two different servers, with different domains. To do this type of a thing, you can't use a normal method because of the limitations set in place by "Same Origin Policy". Same Origin Policy is a security concept for client side programing languages. This policy prevents the client side scripts accessing the pages from different web sites. For an example, if your application is hosted in the "hostA" and a client side script of your application wants to send an Ajax request to a another application that is hosted in "hostB", then this request will be prevented by the Same Origin Policy. To be able to make that type of a request, both host and protocol should be same, according to the Same Origin Policy.

You may get error like "Action 'enable' is not a valid action", "Action 'configure' is not a valid action"......... etc... Reason for this may be, the Zend library is not in the include path. If so add the library path to the include path. Or check whether there are old libraries in any directories of include paths that conflicts with the new one. Check whether there is a one as a PEAR package. And check whether the "zf" c
