ExtJS does not have anything built in to allow the setting of the parameter separator - the use of '&' is in fact the de facto standard.
However, you can change the default behavior if you need to override Ext.Object.toQueryString
Ext.define('Ext.override.CustomQueryString', {
override: 'Ext.Object',
toQueryString: function() {
var queryString = this.callParent(arguments);
return queryString.replace('&', ':');
}
})
