AJAX requests for XML documents fail if the Content-Type is incorrect

If an XML document is sent with the wrong Content-Type (e.g. "text/html"), jQuery will return a parsererror, even if the response body is valid XML. This issue was discovered via a Rails bug in which cached content (in our case, an XML document) is returned with a Content-Type of "text/html" rather than the original Content-Type. See

Thanks for the report, but this is not a jQuery bug. If the server is failing to provide the proper Content-Type header for XML data as required by the XMLHttpRequest spec, it is not jQuery’s responsibility to try to process the input anyway.
