Sys.Net.XmlHttpExecutor.getAllResponseHeaders Method
Returns all the response headers.
Note
To get or set property values for client API properties, you must call property accessor methods that are named with the get_ and set_ prefixes. For example, to get or set a value for a property such as cancel, you call the get_cancel or set_cancel methods.
var statusText = MyExecutor.getAllResponseHeader();
Exceptions
Exception type |
Condition |
|---|---|
The getAllResponseHeaders property was accessed outside the event handler. -or- The getAllResponseHeaders property was accessed after the completed event occurred. |
Remarks
If the request completed successfully, the getAllResponseHeader method returns a string that contains all the response headers. If the request is not successful, an error is returned instead.
You can call the getAllResponseHeaders method only in code that is running inside a completed event handler, or running in the call stack of the completed event handler. An exception is thrown if you call the getAllResponseHeaders method when the executor did not return successfully, or if the XmlHttpExecutor.responseAvailable property returns false. An exception is also thrown if you call the getAllResponseHeaders method after the completed event has occurred. This is because the executor has released releases its reference to the browser's XMLHTTP object.
Example
The following example shows how to get all the headers. This code is part of a complete example found in the Sys.Net.XmlHttpExecutor class overview.
