Error: XMLHttpRequest cannot load

[ridasfa1]

Hi
I am using Ext.Ajax.request({...}) method,
in its url config property i specified url like:
url: 'http://localhost:7878/eric-test/main/receipt/items', and it works fine

but when i replace 'localhost' with my ip address i see this error in the console:

XMLHttpRequest cannot load http://192.168.2.212:7878/eric-test/...ceipt/receipts. Origin http://localhost:7878 is not allowed by Access-Control-Allow-Origin.

what might be the error

i solved like this:
first modified my url to look like: url: '/eric-test/main/receipt/item
that is i removed the server location {ipAddress : portNumber} where the '/' in the begining refers
that we are still in same domain
Second i added method: 'GET' config property to Ext.Ajax.request({}) which was missing

@ridasfa1--

To qualify as a 'same-origin' request, the following conditions must be met:

The protocol (https://) must be the same as origin (page load)
The port must also be the same as origin.
The HOST (DNS-resolved or implicit IP) must also be the same as origin.

Run with it.
